How to maintain the get query param for all template page Django
I have written some adminview for request the data from user and based on that data i put query and populating the data on template. My question is how I have to request data from user once and render template. and till the next data asked. views.py class ReadView(AbstractAdminView): def get(self, request, *args, **kwargs): roll_no = request.GET['roll_no'] roll_obj1 = Roll.objects.get(student__profile=roll_no) return self.admin_render(request, template1, { 'roll_details':roll_obj1 }) class PlayView(AbstractAdminView): def get(self, request, *args, **kwargs): roll_no = request.GET['roll_no'] roll_obj2 = Sub.objects.get(sec__student=roll_no) return self.admin_render(request, template2, { 'roll_details':roll_obj2 }) urls.py {% if request.path == roll_detail %}{% endif %}<a href="{% url 'roll_detail'%}?roll_no={{roll_no}}">ROll Detail</a> {% if request.path == sub_detail %}{% endif %}<a href="{% url 'sub_detail'%}?roll_no={{roll_no}}">Sub Detail</a> SO, what I want, That I have request roll_no once and that should work for both urls template, and when moving from one url/tab to another then it should maintain the data of current roll_no till next roll_no to be entered. -
Django Fixtures: Importing Nested Models
New to Python and Django and trying to import a .json file. The JSON file is structured in such a way that each root-level object has a nested object within it. For example, the JSON is structured as: [ { "model": "testapp.Person", "pk": 1, "fields": { "firstName":"Jane", "lastname":"Doe", "haircolor":"black", "mailingaddress": { "streetaddress": "1214 Example St.", "city": "Silver Spring", "state": "MD", "zipcode": "20910" } } } ] And the python model definition is as follows: from django.db import models # Create your models here. class address(models.Model): streetaddress = models.CharField(max_length=200) city = models.CharField(max_length=200) state = models.CharField(max_length=5) zipcode = models.CharField(max_length=10) def __init__(self, streetaddress, city, state, zipcode): self.streetaddress = streetaddress self.city = city self.state = state self.zipcode = zipcode class Person(models.Model): firstName = models.CharField(max_length=200) lastname = models.CharField(max_length=200) haircolor = models.CharField(max_length=200) mailingaddress = address(streetaddress, city, state, zipcode) Getting an error when running python manage.py loaddata because, obviously, the init parameters streetaddress, city, state, zipcode don't exist in that context. How do I construct my model to dynamically generate those other objects? -

Django ajax redirecting on form submission
I'm trying to return data with an ajax request on a form submission. My goal was too use two views, one too handle the template loading and the other to handle the POST request from the form. In the current state, the form is redirecting to the JSON that is in the callback. That makes sense as it's for the form action url is pointing, however, i want to just pass the data to the current page and not reload the page or be redirected to another page. Here is the code: user.html <form action="{% url 'ajax-user-post' %}" method="post"> {% csrf_token %} {% for user in users %} <input type="submit" name="name" value="{{ user }}"> {% endfor %} views.py def ajax_user(request): # get some data.. if request.METHOD == 'POST': user = request.POST['user'] user_data = User.objects.get(user=user) data = {'user_data': 'user_data'} return JsonResponse(data) def user(request): return render(request, 'user.html', context) urls.py url(r'^success/', user, name="user"), url(r'^ajax/user/', ajax_user, name="ajax-user-post") .js $('form').on('submit', function(){ var name = // the name of the user selected $.ajax({ type: "POST", dataType: "json", url: 'ajax/user/', data: { 'csrfmiddlewaretoken': csrftoken, 'name': name, 'form': $form.serialize() }, success:function(data) { // hide the current data console.log(data); displayUserData(data) } }) }); Thanks for the help in advance! -
Django model field verbose name in template
How would you approach getting a Field verbose name to show up in a template when you are iterating over the fields via a custom array? Suppose you have #models.py class Letter (models.Model): a = models.CharField(max_length=1, verbose_name=u'The Letter and Vowel A') b = models.CharField(verbose_name=u'The Letter and Consonant B') ... y = models.CharField(verbose_name=u'The Letter, Consonant, and sometimes Vowel Y') def vowel_array(self): return [self.a,self.e,self.i,self.o,self.u,self.y,] nothing special in the view: ... return render(request, 'app/view.html', { 'language' : language, 'letters' : letters, }) and in the template {% for letter in letters.vowel_array %} <div>{{letter.verbose_name}}</div> <!-- for 'a' => The Letter and Vowel A --> {% endfor %} My current implementation seems problematic? def vowel_array(self): return [ [self.a, self._meta.get_field('a').verbose_name.title()], [self.e, self._meta.get_field('e').verbose_name.title()], [self.i, self._meta.get_field('i').verbose_name.title()], [self.o, self._meta.get_field('o').verbose_name.title()], [self.u, self._meta.get_field('u').verbose_name.title()], [self.y, self._meta.get_field('y').verbose_name.title()] ] and {% for letter in letters.vowel_array %} <div>{{letter.1}}</div> <!-- for 'a' => The Letter and Vowel A --> {% endfor %} -

How to make related dropdown search filter with Django
So for a while I had trouble with this... I have more models like: Faculty, Department, Study Programme and Courses. Now, based on these models I want to show specific courses. Like for faculty of biology, department of sciences, study programme of science, I want to list all courses in that study programme, specific to the department, specific to faculty. I want to make each of this in a dropdown and then to display results on page. I did some research and found something about using Ajax, but I don't know how to use that thing.

Data intensive application with Django?
I am trying to build a data intensive web application in Django. When I start this django application, I want it load a large amount of data (a few Gigabytes) into memory, and then whenever I receive a request, I will use the preloaded data to do some computation and generate a response based on the complicated calculations. I am wondering what might be the best way to organize this application. What will be the best way to build another layer that running purely on Python and Django can interact with the isolated running Python program for the calculation results. -

Django REST Framework- how can I create or update a foreign key object when POSTing parent
I am currently working on an API view, for a Job Planning system. Each Job, has a single JobPlan (which has a start and end date) and each JobPlan, may have several JobPlanManagers, users assigned to manage said Job. User one might be in charge of one month, and User two might overlap User 1, but extend the job by a couple of weeks. Thus, when User 2 POSTS their new JobPlanManager instance, they need to either create a new JobPlan (if no plan yet exists) or update the existing JobPlan, to extend the start and end appropriately. The user's POST data would include their user ID, the Job ID, and a start and end date, something like: { "manager": (User ID), "job_plan": { "id": null, "job": { "id": (existing Job ID) }, "start": "2018-02-01", "end": "2018-02-28" } } Additionally, I would like the return of this POST call to include all fields for JobPlan and Job, nested: e.g.: { "id": (created JobPlanManager instance ID) "manager": (User ID), "job_plan": { "id": (New or existing JobPlan ID) "job": { "id": (Existing Job ID), "name": "Existing Job Name" } "start": "2018-01-02", "end": "2018-02-28" } } My models look like: class Job(models.Model) name … -

Django: running a python shell in a sandbox environment, similar to rails console --sandbox
Inside my Django project, I want to fire up a python shell wherein I can make simple changes to my database (saving new records, updating old ones, etc.) which are then automatically reverted back when I exit the shell. Essentially the same functionality as running "rails console --sandbox" in a Ruby on Rails project. I'm not looking for all the features of a traditional sandbox such as blocking web-service calls, just the basic database rollback. Is this--or something similar--possible in Django? I want to use this for testing purposes. I know I can use Django's testing infrastructure to do this, but there are some basic instances where this would be very useful (e.g. quickly confirming that a specific model functions the way I expect it to). -
How do I use a CSS attribute's value of an html element as input when submiting a form with Django?
Please first click the link to the image below to understand my question/situation. If the text below a particular species icon (circle with animal image inside it) is bold, I would like that to be used as input criteria for getting information from a database. In other words, I want to use the font-weight CSS property of a element as an input. Only one "species text" can be bold at a time. For example, if I have "D. rerio" selected (its font is bold) and I click the "search" button, I would like for the back-end to know that it needs to pull information from the "D. rerio" database specifically. Click here to see the picture of the situation I described above -

Pre-populating dropdown menus with ViewFlow Material Forms
I am using Django and am trying to get a dropdown menu to prepopulate. This is how I am currently trying to do it in the form: {% if asset.id|stringformat:"s" == pageID|stringformat:"s" %} {% attr form.assetID "option" selected %}"selected"{% endattr %} {% endif %} As you can see, I am trying to select the asset from the dropdown menu if it's ID matches the ID that was passed into the page and change it's selected attribute to "selected" if it matches. I know this isn't the right way to do it but I haven't been able to figure it out otherwise. I have tried overriding {% part form.assetID control %} and putting this code in there but that just removes the dropdown field entirely. Is there a way to do this without just writing the whole field myself? -
Django REST: Automatically update connected model (After POST)
I would like to create an ability for users to exchange 1-to-1 messages. To do this, I would like to update fields in my Django models, depending on actions taken by the Message model. For example, I would like to update the last_message in Conversation model, each time a new message is posted. I have 2 main models: Conversation and Message, where each conversation can have many messages. Models.py class Conversation(models.Model): last_message = models.CharField(max_length=50, blank=True) class Message(models.Model): body = models.TextField(max_length=500, blank=False) conversation = models.ForeignKey(Conversation, on_delete=models.CASCADE) I figured that I need to use the override the save() method in the Message class. def save(self, *args, **kwargs): super(Message, self).save(*args, **kwargs) # something that I need self.conversation.last_message = self.body In the end, I would like to send a POST request to my API endpoint e.g. /api/conversation/<id>/messages/ and it will update the Conversation object with every new latest message. -

Linking two django fields in two different models
I am going slightly crazy as I am sure this is a super simple question. I have two models in django: class Play(models.Model): gid = models.IntegerField() pid = models.IntegerField(primary_key=True) off = models.CharField(max_length=5) deff = models.CharField(max_length=5) type = models.CharField(max_length=10) class FGXP(models.Model): pid = models.IntegerField() fgxp = models.CharField(max_length=5) fkicker = models.CharField(max_length=10) This is a football database and when there is a Play that scores there is another table where additional data about the extra point is held: FGXP. So in Play pid is the primary_key. In FGXP there is a link between pid and the pid in play. In my Django model should I link them? I will end up needing to join the data when I do a query. Thanks - an apologies if a duplicate.
