How can I paginate by a common value with Django and REST Framework?
Background: Hi, folks. I have a model, Transplant, which describes which plant species were transplanted at a given time. Here are my models, boiled down to a simple form: class Species(models.Model): name = models.TextField() class Transplant(models.Model): datetime = models.DateTimeField() species = models.ManyToManyField(Species, related_query_name='transplants') Problem: I'd like to serve results from my API paginated by the date component of my DateTimeField, and showing the date and a list of distinct species. There are an arbitrary number of transplants per day, and transplants are done on arbitrary days. Given the following transplants: [ { 'datetime': '2019-07-01 10:00:00', 'species': ['Lettuce', 'Kale'] }, { 'datetime': '2019-07-01 12:00:00', 'species': ['Basil', 'Kale', 'Chard'] }, { 'datetime': '2019-07-01 15:00:00', 'species': ['Lettuce'] }, { 'datetime': '2019-07-02 11:00:00', 'species': ['Spinach'] }, { 'datetime': '2019-07-02 16:15:00', 'species': ['Lettuce'] }, { 'datetime': '2019-07-05 09:00:00', 'species': ['Lettuce', 'Kale'] }, { 'datetime': '2019-07-05 12:00:00', 'species': ['Arugula', 'Spinach'] }, ] I'd like these results (if page_size = 2): # page 1 [ { 'date': '2019-07-01', 'species': ['Lettuce', 'Kale', 'Basil', 'Chard'] }, { 'date': '2019-07-02', 'species': ['Spinach', 'Lettuce'] }, ] # page 2 [ { 'date': '2019-07-05', 'species': ['Lettuce', 'Kale', 'Arugula', 'Spinach'] }, ] What I've Tried: What I'm doing now is querying for distinct … -

Django and Ajax refreshing a div
I am very new to JS/Ajax and a relative novice to Django. I am testing to see how I can get information back and forth from an Ajax call to my view, and back to Ajax to replace a header string as a simple test. I can receive information back to my view (h1, which is "AJAX TEST"). What I can't seem to get is the h2text to change to "HEADER CHANGED". Any help is appreciated as I don't know if it's my Django return function or my Ajax function. Here is my ajax_test.html: <div class="content"> <div class="center"> <h1 id="h1">AJAX TEST</h1> <div> <button id="btn">PRESS ME</button> </div> </div> <div id="update_div"> {% include "ProdPlat/ajax_test_div.html" %} </div> </div> <script type="text/javascript" src="{% static 'ProdPlat\js\ajax_test.js' %}"></script> {% endblock %} My ajax_test_div.html (which I'm trying to refresh): <div class="content"> <div class="center"> <h2 id="h2">{{h2text.h2text}}</h2> </div> </div> My views_test.py: def test_ajax(request): logger.debug('\n\ntest_ajax FUNCTION:') # return HttpResponse('test_ajax') logger.debug('referer = {}'.format(request.META.get('HTTP_REFERER'))) h2text = {'h2text': "INITIAL HEADER"} if request.method == 'POST': logger.debug('POST request') text = request.POST.get('text') logger.debug('text = {}'.format(text)) h2text = "HEADER CHANGED" dict = { 'h2text': h2text, } # return JsonResponse(dict) # return render(request, 'ProdPlat/ajax_test_div.html', {'h2text': h2text}) return render_to_response('ProdPlat/ajax_test_div.html', dict) return render(request, 'ProdPlat/ajax_test.html', {'h2text': h2text}) And finally my Ajax call: … -

Why is the format parameter for a HyperlinkedIdentityField page set to "api" when I have explicitly defined it as html in serializers.py
I'm trying to use a HyperlinkedIdentityField to display a link for a field within a serializer. The link is correct on the except for the suffix of ?format=api when it should be ?format=html. I'm using a DefaultRouter for myapplication/urls.py, this might be the cause of my problems, but I don't what to do in order to solve the problem class SnippetSerializer(serializers.HyperlinkedModelSerializer): owner = serializers.ReadOnlyField(source='owner.username') highlight = serializers.HyperlinkedIdentityField(view_name='snippet-highlight', format='html') And in the browser, the JSON format of a model previously created is displayed as: { "url": "http://127.0.0.1:8000/snippets/1/?format=api", "id": 1, "highlight": "http://127.0.0.1:8000/snippets/1/highlight/?format=api", "owner": "admin", } When the link is clicked, the user is linked to a 404 error, however, if the link is manually updated to http://127.0.0.1:8000/snippets/1/?format=html everything is displayed as expected -

How can i use more different forms in the same Django template?
In my project, i have a template where i'm trying to put two forms for different use cases. I've never come across this problem before, so i don't really know where to go from here to use two forms in the same page. At first i thought of creating another view to handle each form, but i think that this solution would create problems with the rendering of my templates, other than not being sustainable if i should have this problem again with another template. After making some research, i found a solution but it works for class based views, but i'd like to avoid that since my view is already a function based view, and i would have to make a lot of changes in my code. Would it be possible to solve this problem with a function based view? Every advice is appreciated First field class FirstForm(forms.ModelForm): firstfield = forms.CharField() secondfield = forms.CharField() class Meta: model = MyModel fields = ("firstfield", "secondfield") def save(self, commit=True): send = super(FirstForm, self).save(commit=False) if commit: send.save() return send** Second Form class SecondForm(forms.ModelForm): firstfield = forms.FloatField() secondfield = forms.Floatfield() thirdfield = forms.CharField() class Meta: model = MyModelTwo fields = ("firstfield", "secondfield", "thirdfield") def … -
Apply Autocomplete=off to Django password reset confirm form
I am using Django 2.2 with Python 3.7 Following a security audit, I have been asked to ensure all security-related fields on forms in our application render with the autocomplete="off" attribute. Whether or not this is a valid and useful security measure is out of scope... unfortunately. So far, I have accomplished this by extending the form in question. For example, with the PasswordResetForm (where the user enters the email associated with the account): class NoAutocompletePasswordResetForm(PasswordResetForm): def __init__(self, *args, **kwargs): super(PasswordResetForm, self).__init__(*args, **kwargs) self.fields['email'].widget.attrs.update({'autocomplete': 'off'}) And then instructing the relevant auth view to use it like so (in urls.py): url(r'^accounts/password_reset/?$', auth_views.PasswordResetView.as_view(form_class=forms.NoAutocompletePasswordResetForm)), This worked fine up until the Password Reset Confirm View, which uses the SetPasswordForm. The first attempt there went something like this: url(r'^accounts/reset/(?P<uidb64>[0-9A-Za-z]+)/(?P<token>[0-9A-Za-z\-]+)/$', auth_views.PasswordResetConfirmView.as_view(form_class=forms.NoAutocompleteSetPasswordForm)), class NoAutocompleteSetPasswordForm(SetPasswordForm): def __init__(self, *args, **kwargs): super(SetPasswordForm, self).__init__(*args, **kwargs) self.fields['new_password1'].widget.attrs.update({'autocomplete': 'off'}) self.fields['new_password2'].widget.attrs.update({'autocomplete': 'off'}) However this just yields a TypeError, on the super() line, with the detail that __init__() got an unexpected keyword argument 'user', despite the presence of a named user argument to the init of that form, as seen in the Django source. But for funsies, I tried passing the user as a positional arg instead, like so: class NoAutocompleteSetPasswordForm(SetPasswordForm): def __init__(self, *args, **kwargs): … -
How To Save Table Data on Form Post (Django)
I have a table nested within a form where each HTML element is populated by iterating throughout various records stored in a local database. The user may make changes to one or more elements. On POST I want to submit and save the data for the edited table row only, as the table will include many rows. I will reference what record to be updated by the attribute id which is stored within a hidden div. For readability, I have only included one example of the HTML elements within the table. More than anything, I am looking for guidance on how to best implement my solution. For example, how can I specify a particular row to be saved? Will this solution require jQuery or AJAX? views.py def update_table(request): id = request.POST.get('id') obj = Opportunity.objects.get(id=id) account_manager_id = request.POST.get('account_manager') form_class = CreateOpportunityForm if request.method == 'POST': form = form_class(data=request.POST) if form.is_valid(): try: obj.accountManager = account_manager_id obj.save() except Opportunity.DoesNotExist: obj = None context = { } return render(request, 'website/opportunity_dashboard.html', context) template.html <form action="{% url 'update_table' %}" method="post" name="opportunityTable"> {% csrf_token %} <div class="table-container"> <table id="opportunityTable"> <thead> <tr> <th>Account Manager</th> </tr> </thead> <tfoot> <tr> <th>Account Manager</th> </tr> </tfoot> {% for object, opportunity, account_manager, presales_engineer, … -
Having trouble over-riding style on bootstrap components
I cannot get my custom css to override any of the components of Bootstrap4 in Django project. I am very new to front-end development and hope that I can ask this question clearly. note: This is an html sheet in a Django project. My custom css sheet is linked properly as I can use it successfully on other components (non-bootstrap) of the page. The only way I have been able to override any of my bootstrap components is by including the style as an html attribute as seen in the example below where I made the background of the first row blue. I have been working on solving this issue for a couple of days now and the only things I seem to find is to make sure your custom style sheet is loaded after the Bootstrap style sheet. I have my home.css sheet loading after the bootstrap css, but I am not sure if the way Django loads these is interfering with the order. Any help or suggestions on trouble-shooting this would be greatly appreciated. Thank you. {% load staticfiles %} <head> <!-- Bootstrap core CSS --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous"> </head> <link rel="stylesheet" href="https://fonts.googleapis.com/css?family=Lato&display=swap" > <link rel="stylesheet" … -
How to initialize the database with your test data for each module? Pytest-django
For each application in the project, you need to write tests. Also for each application you first need to upload your test data, which, after passing all the module tests, must be deleted. I found several solutions, but none of them seems to me optimal First: in file conftest.py in each app I override method django_db_setup , but in this case, the data is not deleted after passing the tests in the module, and become available for other applications. In theory, with the help of yield you can delete all the data after passing the tests. def django_db_setup(django_db_setup, django_db_blocker): with django_db_blocker.unblock(): call_command('loaddata', './apps/accounts/fixtures/accounts.json') call_command('loaddata', './apps/activation/fixtures/activation.json') call_command('loaddata', './apps/questionnaire/fixtures/questionnaire.json') yield delete_test_data``` Second: ``` @pytest.fixture(autouse=True) def setup(self, db): call_command('loaddata', './apps/accounts/fixtures/accounts.json') call_command('loaddata', './apps/activation/fixtures/activation.json') call_command('loaddata', './apps/questionnaire/fixtures/questionnaire.json')``` In this case, the data will be loaded exactly as many times as there will be tests in the module, which also seems to be not quite correct. -
Form onsubmit which places an ajax call does not return before the form goes to its action. However works on mac but not PC
I am building an application in Django that creates rubrics to grades assignments. Each rubric item is editable and on submission of the form, the page is checking if a rubric item has been edited and if it has editing it in the database. Then once all those have been updated, it will submit the checked checkboxes as the grade. So the form action is to submit the grade, and in the jquery I have an event listener checking for when the submit button is clicked that will make an ajax call to update the rubric entries. The rubric entries arent being edited before the form goes to its action. Like its going to the form action too quickly the jquery doesnt have time to finish. I've tried doing event.preventDefault to prefent the form from going to the action and then submiting the form after the loop that edits all the rubric entries which should give it time to finish. I've also tried calling this function in an onsubmit instead of an onclick because I heard that the onsubmit executes before the form action does. But here's the thing. The code works perfectly on my mac, but does not work … -

Django Dynamic Search with Multiple Values
I am creating a site that a user can search for multiple ingredients and look up recipes with those ingredients. There will be a single search bar with 2 buttons, 'Add' and 'Search'. the Add button will add the ingredients to a list, and search will redirect them to a page of results. As users add ingredients I have them being updated in a list below the search bar and saving the values in a javascript array, this works good and I can see the array being updated when I print to console. My error comes when I hit the Search button. I am sending the Javascript array back to the server through AJAX. The request come back successfully and I can get the data back and convert it to a python list. However, I cannot render a new view. It doesn't give me errors, it just stays on the home page after pressing submit. I believe I have to send a JsonResponse back to frontend, but when I do that I lose the reference to the array that I need to render the next page. Is there a way I can save the array that I am given through … -
Using a modal to select quatities

Field required when using two forms in Django

Invalid literal for int() with base 10 : "some string", but the field in question is a foreign key to a charfield

If I try to query the the Progress class it works fine, but when I search for a value for progress within the Tasks class I get the error. I have already tried clearing my my migrations and re-migrating, it had no effect. class Program(models.Model): name = models.CharField(max_length=30) class Tasks(models.Model): program = models.ForeignKey(Program, max_length=30, on_delete=models.CASCADE) Shell >>> from app.models import * >>> a = Program.objects.filter(name="GM") >>> print(a) <QuerySet [<Program: GM>]> >>> a = Tasks.objects.filter(program="GM") ValueError: invalid literal for int() with base 10: 'GM' I should be able to grab this object and manipulate it, I am certain that there is an object with program set to "GM". -
mutex on different instances of django model
I'm creating a django-docker project where each user has their own docker container running an agent that manages their blockchain wallet. The problem I'm running into is that sometimes the server needs to start a container to manage user connections, and the user starts their docker container on login as well. If the server and the user both logout at the same time, it may try to delete a container twice. likewise if the user and the server start a docker container at the same time, we would have two copies of the same docker container running. I've used a couple semaphores and a lock to solve the problem on paper, but I'm wondering if I create two agent objects using: agent_obj_1 = agent.objects.get(wallet_name=request.session["wallet"]) agent_obj_2 = agent.objects.get(wallet_name=request.session["wallet"]) agent_obj_1.start() agent_obj_2.start() where each agent has a lock and semaphore local variable, and I lock the mutex on agent_obj_1, can I still lock agent_obj_2 because they are different instances? or can I not lock agent_obj_2 because it is only a different referance pointing to the same object in memory as agent_obj_1? ie. do agent_obj_1 and agent_obj_2 share a lock instance variable defined in the __init__() method? here is the relevant part of my … -
How to Save Table Row On Change (Django/Ajax)
I have a table which is populated by iterating over various records in a local database. Nested within the table data are divs which hold different HTML objects such as textboxes and dropdown menus which are subject to user input. Upon a change to one or more of these elements in a particular row, I would like to update the database record with the data in the table row. Do I need individual AJAX payloads for each HTML element for which I want to save data? Or am I able to assign an ID to the table to reference in my AJAX? If so, then how would I specify which row needs to be updated since rows are dependent upon the iteration which creates them? template.html <table class="table is-fullwidth is-striped is-bordered"> <thead> <tr> <th>Header 1</th> <th>Header 2</th> <th>Header 4</th> <th>Header 5</th> </tr> </thead> <tfoot> <tr> <th>Header 1</th> <th>Header 2</th> <th>Header 3</th> <th>Header 4</th> <th>Header 5</th> </tr> </tfoot> {% for object, opportunity, account_manager, presales_engineer, inside_solution, time in object_zip %} <tbody> <tr> <th> {{ object.opportunityId }} </th> <td> <div class="select"> <select name="status" id="cw_status"> <option value="{{ opportunity.status.id }}">{{ opportunity.status.name }}</option> <option value="Lost">Lost</option> </select> </div> </td> <td> <div class="select"> <select name="account_manager" id="account_manager"> <option value="{{ …
