Django - OneToOneField Not Populating in Admin
I’m trying to get the username of the current logged in user using OneToOneField to populate in the admin once the user submits a form. The username should go in the user column of admin.py. I’ve tried various methods and still no luck. I’m new to this and this is my first Django application I’m building so I’m not sure what I’m missing. I’m stuck and have no idea what I’m doing so any help is gladly appreciated. Can someone please help? What am I missing? Thanks!

Django - Variable is not getting send with POST request
Hey im using for my django project typescript to get a specific section from a text to my view but it somehow doesnt work and I dont really know why. Here is my template in which I want the "currentgap" sent to my view after clicking on the submit button. The getSelectionText() method just sets the id 'gap' to a specific string: <form action="editorgapcreate" id=create method="POST"> <script src="../static/textselector.js"></script> <div id="app" onmouseup="getSelectionText()"> This is a test section. </div> {% csrf_token %} <b>Your current selected gap:</b> <p id="currentgap"></p> <input type="hidden" name="gap" id="currentgap"> <button type="submit" name="create_gap">Create gap</button> </form> and here is my view in which I tried calling it: def editorstart(request): if request.method == 'POST': gap = request.POST['gap'] print(gap) return render(request, 'editor_start.html') else: return render(request, 'editor_start.html') The first time using currentgap in my template it displays it correctly but trying to send it to my view with a POST request doesnt work and the print is empty and I dont really know why. -

Django - Render is not working in my project
I am dealing with form like 1 week but couldn't solve my issue. Probably i overlook something that can be found easy by other eyes, but totally, i don't know what to do. I recognize problem by starting build form. I had to use render for form and it failed in every try. I am able to connect db and showing data in html pages but whenever i use render instead of render_to_response it is failing. And i had to use render for post request as i know. Not only for form, render is not working for all. Even for a simple: def home(request): context = {'foo': 'bar'} return render(request, 'main.html', context) models.py class ModuleNames(models.Model): ModuleName = models.CharField(max_length = 50) ModuleDesc = models.CharField(max_length = 256) ModuleSort = models.SmallIntegerField() isActive = models.BooleanField() ModuleType = models.ForeignKey(ModuleTypes, on_delete=models.CASCADE, null = True) slug = models.SlugField(('ModuleName'), max_length=50, blank=True) class Meta: app_label = 'zz' def __unicode__(self): return self.status forms.py from django import forms from MyApp.models import ModuleNames class ModuleForm(forms.ModelForm): moduleName = forms.CharField(label='Module Name', max_length=50) ModuleDesc = forms.CharField(max_length = 256) ModuleSort = forms.IntegerField() isActive = forms.BooleanField() ModuleType = forms.IntegerField() class Meta: model = ModuleNames fields =('moduleName','ModuleDesc','ModuleSort','isActive','ModuleType') view.py from django.views.generic import TemplateView from django.shortcuts import render,render_to_response, redirect from … -
Rendering forms with django-semanticui-forms and confused with how choice fields work
I'm using the module django-semanticui-forms to render my forms in a nice format with SemanticUI. I'm confused about what they're doing with choice fields and how to use it in my own code. CHOICES_1 = ( (0, "Zero"), (1, "One"), (2, "Two"), (3, "Three"), (4, "Four"), (5, "Five"), ) class Choice(models.Model): choices_1_1 = models.IntegerField(choices=CHOICES_1) When I render the form, I'm able to choose between the six options and when I output the choice on a html form like {{user.choices_1_1}}, I get an integer. This makes sense because the model has an IntegerField here. How do I get the value associated with this integer key though? Is there an easy way to print "Zero" instead of 0 without casing on each integer and rendering the string that way? Lmk if the question is confusing -

All accordions opening at once using Django
This is a really silly question, but I can't find the answer anywhere! I have a for loop & for each item, it creates an accordion as below. The problem is, the accordion always has the same ID, so when I toggle one to open, they all open. How can I systematically assign each a different value, so they open independently? <td colspan="5"> <div id="accordion"> <div class="card"> <div class="card-header" id="headingOne"> <h5 class="mb-0"> <button class="btn btn-link" data-toggle="collapse" data-target="#collapseOne" aria-expanded="false" aria-controls="collapseOne"> <font color="black">Edit Task</font> </button> </h5> </div> <div id="collapseOne" class="collapse" aria-labelledby="headingOne" data-parent="#accordion"> <div class="card-body"> <form action="/update/" name="form1", id="form1" method="post"> {% csrf_token %} <div class="form-group"> <select name="assignee" class="form-control" id="exampleFormControlSelect1"> <option>Select Assignee</option> <option>kikee</option> <option>kieran</option> <option>4</option> <option>5</option> </select> </div> <div class="form-group"> <select name="priority" class="form-control" id="exampleFormControlSelect1"> <option>Select Priority</option> <option>High</option> <option>Medium</option> <option>Low</option> </select> </div> <div class="form-group"> <input type="text" name="due" class="form-control" id="task" aria-describedby="emailHelp" placeholder="Due Date YYYYMMDD"> </div> <button type="submit" name="editbutton" value={{ todo.taskid }} class="btn btn-warning">Edit Task</button> </form> </div></div></div> </div> </td> -

Display process list in Django template

Django model objects do not load in Form in testing environment
Using Django 2.1.3 Getting a strange error here; I have a form multiplechoicefield that draws its choices from the values existing in a model in the database. class ChartForm(Form): P_CHOICES = tuple((p["p"], p["p"]) for p in VAR.objects.all().values("p")) p = MultipleChoiceField(widget=CheckboxSelectMultiple, choices=P_CHOICES, initial=P_CHOICES[0][1]) I am trying to run tests for a different app in the project. It throws the following error: File "/code/pyyc/forms.py", line 31, in ChartForm p = MultipleChoiceField(widget=CheckboxSelectMultiple, choices=P_CHOICES, initial=P_CHOICES[0][1]) IndexError: tuple index out of range I assumed it was just because the model objects weren't loaded. So I added in the fixtures from the VAR app. And yet, it still throws the error. Presumably, the Form is render before the test database is compiled ... ? So I am now editing the Form so that P_CHOICES is done manually, but this is obviously not ideal for the test environment. Anyone ever come across this? Is there a smart hack for this that doesn't involve commenting out lines in the Form every time you want to test? -

Pandas groupby sum doesn't keep the other columns using Django
I have a problem using this line of code: user_metadata = user_metadata.groupby(['user_id', 'gender', 'age']).sum().reset_index() I have a dataframe with almost 120 columns, I need to keep user_id, gender and age, and then sum all the values of each column and keep all the 120 columns. I used this in jupyter and it works completely fine and it keeps all 120 columns. But I need to use it in django platform. So I use the same code in django, but it just keep 5 columns and dropped all other columns. (These 5 columns contain characters in their name while the others contain numbers.)

Is there a simple way to create Chained Dynamic Drop Down List in Django Admin Site?
at this moment I am creating a project to learn how to use django. In this project there are three models: Category Subcategory Product And what I'm trying to achieve is to dynamically choose the corresponding subcategory after selecting the category, and thus be able to add the product. I tried to use smart_selects without results, since it is not compatible with python 3.7 I tried to filter the list of subcategories using the selected category field as a filter, without success, I think I am not formulating the code well, so that it takes the value of the category field to filter the list of subcategories dynamically.

Now, when I enter the old password, new password and confirm password fields in the built-in template and hit enter(or submit) I get a "no reverse match" error saying "Reverse for 'password_change_done' not found. 'password_change_done' is not a valid view function or pattern name." I have researched a lot and found out that its because I am using the application namespace(app_name='authenticationApp' in urls.py) thats why django is not able to find the reverse. My simple question is How do I let the built-in template know that its supposed to use namespaced URL in the reverse function ? PS: I know using my own template would resolve the issue.
