ng-repeat returns blank rows into table
I am trying to populate a table with JSON data from my Django rest framework API utilizing http.get(). I cannot seem to get it to return anything besides the number of blank rows that I have data for. i.e. There are 9 reservations and I get nine blank rows. I do get the data back from the server on the console.

Unable to use objects from a module in sys.modules
Because of circular dependencies a want to load a module this way: try: from ..foo import serializers as foo_serializers except ImportError: import sys foo_serializers = sys.modules['app.foo.serializers'] When I use the loaded module in a class definition like this, it says app.foo.serializers has no attribute OtherSerializer although it definitely has: class SomeSerializer(ModelSerializer): some_field = foo_serializers.OtherSerializer() But when I use foo_serializers.OtherSerializer in a class function it works. What does it mean? Are modules in sys.modules fully loaded in the time when the class definition is loaded? What could be a problem here? -

Why do I need to use {% static to render js files on index build by webpack? (CloudFront, production) webpack django vue cloudFront beanstalk
Im currently trying to upload into production (beanstalk) my Django app, using webpack to wrap a vue app. The problem is that locally works perfect, I can render the text, style, js files, etc. but when I upload the code to production, the file "index.html" (the output from webpack) render, but the js and css files don't. When I add manually the tag for static ({% load static %}) and upload the code, the view render the "index.html" file and the js, css files also. Why do I need to add the static tag on production? what am I doing wrong? On production (beanstalk) I use CloudFront as CDN for static files, and when I debug beanstalk (eb logs) I see a 404 code trying to render the js, css files (with the other images that render with django template system, that render ok, i don't see any message, not even a 200 code (I suppose this is because the CDN deliver the files)) What code/debug logs/config should I upload here? Thanks! -
How to debug long wait times for Django Website
I have a Django website whose response time I would like to improve. When I click intra-site links on my site the result is either an immediate loading of the next page or a 20-30 second wait before the page loads. I find no reproducible patterns in this behavior to help me identify a fix. I realize that there are many, many reasons why this might be the case and much more information on my specific configuration would be required for specific help in this area. However, instead of dumping pages of config info and asking for specific suggestions, I hope others can provide suggestions as to general areas I should investigate that would be consistent with the following observation: Debug-Toolbar shows that total CPU time & SQL query times are in a reasonable range (< 1 sec), however the total browser request time is 22 seconds (see image). Why might these values be so different? What might account for several seconds of request time that wouldn't also fall under CPU-time? -

Django and Ajax refreshing a div

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".

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?

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 …
