Django form missing fields
I'm trying to get a simple form working. Oddly, other forms I wrote in this app are working fine, but this one wont show the fields. Can anyone tell me what I'm missing? Here are the files views.py: def newnote(request, record_id): if request.method == 'POST': form = NoteForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect('/tracker/all/') else: form = NoteForm() return render(request, 'tracker/noteform.html', {'form': form}) models.py class Note(models.Model): record = models.ForeignKey(Record, on_delete=models.CASCADE) note_text = models.CharField('Notes', max_length=2000) note_date = models.DateField('Date Entered') forms.py class NoteForm(forms.Form): class Meta: model = Note fields = ['note_text', 'note_date' ] template (noteform.html) <form action="/tracker/newnote/" method="post"> <div id="fields"> {% csrf_token %} {{ form }} <input type="submit" value="Submit" /> </div> </form> One other note, I have commented out the div id called "fields", to rule out CSS as the issue. -
Reverse Language Translation in Django
I'm building an API using Django Rest Framework that needs to support multiple languages, we're trying to use the Django translation framework, and using the answer from here I've decided how to implement translatable choicefields. However my issue is for the reverse case. Say I have a model like this: from django.utils.translation import ugettext_lazy as _ class Payment(models.Model): OPEN = 0 CLOSED = 1 BALANCE = 2 STATUS_CHOICES = ( (OPEN, _('open')), (CLOSED, _('closed')), (BALANCE, _('balance')), ) status = models.IntegerField(choices=STATUS_CHOICES, default=OPEN, verbose_name=_("Status")) This works fine for returning the information to the user, we use the stored status value and translate it before returning. However, I also want the user to be able to POST a new payment object using any language. So if the user wants to create an open transaction, they can send {'status':'open'} but they can also send it in Spanish as {'status':'abierto'}. Is there a way to handle this automatically? Basically I want to get the reverse of the ugettext_lazy function. -
styling django-userena templates
I have installed django-userena to manage profiles and accounts on my django app. It seems it is not fully configured and I am still working on. One of the problems that I am trying to solve is to figure out how to style the templates. For instance, this is the address for login on a development server: http://127.0.0.1:8000/accounts/signin/ and here is the sign in page, so my question is: How can I style the templates? It seems the templates should be styled by twitter bootstrap or maybe there are some css files that I can place them in my css folder? -
Django, upload image error
In my aplication, the users can change their profile data, like full name, gender, profile image and other stuff. The problem is when the user want to keep the same profile picture and the file input is empty. How do I support that in my view. Here is my html updateProfile.html <form action="{% url 'updateprofile' %}" enctype="multipart/form-data" method="POST">{% csrf_token %} <input type="file" id="logofile" name="avatar" accept="image/gif, image/jpeg, image/png" value=""> <input type="text"name="full_name"> <input type="date"name="birthdate"> </form> Here is my views.py updateprofile def updateprofile(request): #HERE IS WHERE I CHECK IF I CHANGE THE IMAGE OR NOT BUT THIS NOT WORKS IF THE FILE INPUT IS EMPTY if request.FILES['avatar']: avatar = request.FILES['avatar'] full_name=request.POST['full_name'] birth_date= request.POST['birthdate'] c = user.objects.get(id=request.session['account_id']) c.full_name = full_name c.avatar = avatar c.save() return redirect('userprofile') If I change the file in the file input everything works well. But If I don't upload a new Image and leave the file input in blank I have an error. How do I check if there is file or not in the POST request? please help -
how to filter search on contenttype in django
I have a listapiview, and I want to search in a model object. Say the model is ContentTypeObj and there are 3 models limit to it. The 3 other models have a GenericRelation to it.

Django admin linking me to a template
When programming locally on my development server, the site is functioning as expected. But when I go to my production site, a handful of the links in mysite.com/admin link me to a random template that's extending my base.html, rather than the typical database/form UI. For example, I expect this: But instead, I am getting: Any help would be great. -

'Welcome' message from Nginx shown when I run my wsgi Django project + Nginx + Gunicorn
I'm beginner in Django and I've finished my first project.

How to filter a QuerySet to max members of each group in django?
The model is something like this: class Application(models.Model): application_id = models.IntegerField() version_id = models.IntegerField() # some other attributes where application_id and version_id together determine an Application entry, in that one application may have several versions, and an entry with the largest version_id is the application's current version. And the goal is to find the current versions of all applications. The SQL (in MySQL) is something like: SELECT * FROM application AS app WHERE version_id = (SELECT max(version_id) FROM application WHERE application_id = app.application_id); How to achieve this? Please note that the object here is to filter the QuerySet, rather than only fetching the largest version_id, which would be as simple as using a GROUP BY, or in django a values() followed by an annotate(). I'm interested in the other attributes of the current version as well. -
Is it possible to do arithmetic operation on OuterRef expression?
I'm building an Experience booking system in django and I've the following models. class Experience(models.Model): name = models.CharField(max_length=20) capacity = models.IntegerField() class Booking(models.Model): experience = models.ForeignKey(Experience) occupied = models.IntegerField() Each experience has a limited number of capacity and when user perform booking, it will be added to the Booking table with occupied number. Now how will I find the experiences which are not occupied completely? available_experiences = Experience.objects.all().exclude(id__in=Subquery(Booking.objects.filter(occupied__gt=OuterRef('capacity') - request_persons).values_list('experience', flat=True))) Here, request_persons is the number of required vacancy in an experience. This is not working and showing an error like 'ResolvedOuterRef' object has no attribute 'relabeled_clone'. Is it possible to do arithmetic operation on OutRef() expression like F()? Without adding request_persons, the above code works. Why it is not possible to add a value to the OutRef() expression? NOTE: My actual code is much complex one and it will be really great to get an answer without modifying the entire structure of the above code. -
Django 1.11: Issues with utf8 writing to file on windows
I am trying to write some text into a file with data from django objects (CharField) and some formatting. The problem is with accentuated characters (é in the example below). On Linux I have no problems. However, on windows 7, I am getting extremely confusing behaviours. This (open call without encoding): from usermod.models import User user = User.objects.get(pk=134) with open('test.txt', 'w') as fout: fout.write(user.birth_place + ',') fout.write('Séoul') fout.close() produces: SxE9l,Séoul while this (open call with encoding): from usermod.models import User user = User.objects.get(pk=134) with open('test.txt', 'w', encoding='utf8') as fout: fout.write(user.birth_place + ',') fout.write('Séoul') fout.close() which produces: Séoul,Séoul Of course, the expected result is: Séoul,Séoul and this is what I get on Linux with the same database. So the weird thing is that each of those options gets different parts right and wrong. In one case the ORM retrieved value is wrong. In the other it is the string object created in the source code that is wrong. I can't find a way to get both right. All the files are encoded in UTF8 (as reported by notepad++). The python version is 3.5.4 The MySql database has all encodings in UTF8 and an SQL query on the user table shows the … -

Django page for selecting model instances and adding them to a list
I am a beginner with Django, and my JS/HTML/CSS knowledge is intermediate. I have two models defined in models.py: One model Product that has some basic descriptive Fields (name, description, ...), and another model Category, that has a ManyToManyField products. I want to build a page where a user can select Products with checkboxes, and then add them to a category by pressing an "Add" button. Upon pressing, what should basically happen is: category.products.extend( selected_products ) # This only so that I know to which category a product has been assigned, not too urgent for product in selected_products: product.categories.append(category) Here is an image of what sort of page I am aiming for: https://i.imgur.com/BWs0eV0.png I am not asking for a full working example (unless there already happens to be one available of course). All I am looking for is some pointers on how to proceed creating this. I know how to create the list and the sidebar, but combining this with buttons per list element is new to me. Should the proposed page be essentially 1 giant form, and should I define it in forms.py? Should I be using the Django CheckboxInput widget? Is there a recommended structure for this type … -

Web Frameworks: Frontend vs Backend

Template form does not render in Django

Filter on variable of ManyToMany-field inside Django Template
I have a job-object and a content-object. A job object gets created when a user wants to retrieve a set of content-objects in exchange for credits. models.py: class JobId(models.Model): user = models.ForeignKey(User, blank=True, null=True, default=None) job_time = models.DateTimeField(auto_now_add=True) class content(models.Model): job_id_list = models.ManyToManyField(JobId , related_name='JobId', blank=True) job_id_list_not_provided = models.ManyToManyField(JobId , related_name='JobIdFailed', blank=True) free_content = models.CharField(max_length=500, null=True, blank=True) paying_content = models.CharField(max_length=500, null=True, blank=True) For all content-objects part of the job, the JobId-object is added to the job_id_list - not keeping credit levels in mind. Different user can all run multiple jobs on the content objects. For too-big jobs exceeding the credit amount of the user, the content-objects that would push the credit level below zero, get also the JobID-object added to the job_id_list_not_provided field of the content-object. For a a specific user, we can retrieve the two sub-sets of found and not-found content-objects with following queries: views.py: found_results_list = results_list.filter(job_id_list_not_provided__user= None).distinct() not_found_results_list = results_list.filter(job_id_list_not_provided__user=request.user).distinct() My challenge: Result lists are over 100-objects in size, so I would like to use pagination to get a nice view on my page When not considering pagination, I could simply pass the 2 lists (found and not found) and loop over each list with a template … -
Django 2.0 - DateArchiveView date object for template
My app has ArchiveIndexView, YearArchiveView, MonthArchiveView and DayArchiveView. Except in ArchiveIndexView, I wanna add a Back link which will point back to its successor in all the views.

But in DayArchiveView, there is no date_list attribute as of Django 2.0 documentation so how can I implement date object to be used in the template? -
django like button counting irregularly
I have a django application where I implemented a like button for posts posted on the blog. I recently discovered that when ever a like button is clicked by a registered user, the like increases exceedingly. Instead of the number of likes to get increased by 1 it increases by maybe 90+ and when the button is clicked agin for it to change to unlike it still increases so the like function becomes uneven. Below is my code for the like function Html {% with total_likes=obj.likes.count likes=obj.likes.all %} <span class="count"> <span class="total">{{ total_likes }}</span> like{{ total_likes|pluralize }} </span> <a href="#" data-id="{{ obj.id }}" data-action="{% if request.user in likes %}un{% endif %}like" class="like button"> {% if request.user not in users_like %} like {% else %} unlike {% endif %} </a> JQuery <script> var csrftoken = $.cookie('csrftoken'); function csrfSafeMethod(method) { // these HTTP methods do not require CSRF protection return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } $.ajaxSetup({ beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } }); $(document).ready(function(){ $('a.like').click(function(e){ e.preventDefault(); $.post('{% url "posts:like" %}', { id: $(this).data('id'), action: $(this).data('action') }, function(data){ if (data['status'] == 'ok') { var previous_action = $('a.like').data('action'); // toggle data-action $('a.like').data('action', previous_action == 'like' ?

Django save multiple view variables
I'm trying to save URL parameters to my model. Already tried many things and currently getting argument error. Can't find proper documentation on this most likely because I am not sure what the proper search term is. All I need to do is save webhook POST to my URL. I will use @require_POST decorator to require POST only. Atm this is not the issue.

Django admin TabularInline disable fields based on values
I am looking to disable fields in Django Admin TabularInline forms. My model has an optional end_date field which should, if set disable the input fields to avoid further modifications of values. Currently I tried modifying get_formset, but I am unable to get the values to finally disable fields using e.g.: formset.form.base_fields['contract_number'].disabled = True I am using the following code: class ServerLicenseInline(admin.TabularInline): model = ServerLicense autocomplete_fields = ('contract_number',) ordering = ('start_date', 'end_date') extra = 0 can_delete = False def get_formset(self, request, obj=None, **kwargs): formset = super(ServerLicenseInline, self).get_formset(request, obj, **kwargs) ... I was looking in obj and formset to find the values but without chance right now. Does someone have an idea how to achieve this? Thanks!
