Get User object upon successful activation of their account via activation link
I am using django 1.11 & django-allauth to authenticate users. Recently the need to improve the flow when the user registers came up, while the confirmation link in email needs to automatically login the user who is being activated. Based on the documentation there is a setting which only works for same session users. ACCOUNT_LOGIN_ON_EMAIL_CONFIRMATION (=False) The default behaviour is not log users in and to redirect them to ACCOUNT_EMAIL_CONFIRMATION_ANONYMOUS_REDIRECT_URL. By changing this setting to True, users will automatically be logged in once they confirm their email address. Note however that this only works when confirming the email address immediately after signing up, assuming users didn’t close their browser or used some sort of private browsing mode. But - I want to be able to auto-login users upon activation: who have signed up from another form on a different web application (different session) - this will always return that the user is an AnonymousUser. More specifically, on my complete_account_verified_view() definition I want to be able to retrieve the user object of the user associated with the successful activation of their account using that activation link. How can this be implemented or is it not possible - are there any security … -
create embedded forms in django view
I have a rule class, a rule is a combination of a question and an answer: class Rule(models.Model): name = models.CharField(max_length=32) class Question(models.Model): name = models.CharField(max_length=32) rule_id = models.ForeignKey(Rule, on_delete=models.CASCADE, null=True, blank=True) class Answer(models.Model): name = models.CharField(max_length=32) rule_id = models.ForeignKey(Rule, on_delete=models.CASCADE, null=True, blank=True) I want to create a form for the rule, where I have two inputs: one for the question and the other for answer. When I click submit I should save a rule in rule table, a question in question table and an answer in answer table. This is the farest I get: I created a form for each model, and I called those forms in one view method: def create_rule_view(request,id, sc_id): rule = RuleForm(request.POST or None) question= QuestionForm(request.POST or None) answer = AnswerForm(request.POST or None) if rule.is_valid() and question.is_valid() and answer.is_valid(): rule.save() question.save() answer.save() return redirect('../') context = { 'rule': rule, 'question': question, 'answer': answer } return render(request, "rule/create_rule.html", context) But it's not the view I want and each model is saved independantly. Can anyone find a solution for me? thanks. -

Django templates: xxx-jqgrid-yyy notation in url tags
I had asked similar question before in a wider context, now I reduce it to bare bones. My setup (in a conda env): Mac OS X el Capitan 10.13.6 Python 3.6 (also tried with 3.4) Django 1.8.3 jquery-1.11.0.min.js I have an django application that does not work now (legacy inherited from someone else) that used to work. The app employs this data access approach using jqgrid (url tags with xxx-jqgrid-yyy pattern): var searchable_columns = { alteration_type: { searchoptions: { dataUrl: '{% url 'item-jqgrid-Entity1' pk=original.id %}' } }, disease: { searchoptions: { dataUrl: '{% url 'item-jqgrid-Entity2' pk=original.id %}' } }, } where Entity1 and Entity2 are model names, and the urls used to get rendered as dropdowns with values from the models. There is no python code in the app that is referring to this pattern in any way (including url patterns) Question: does this xxx-jqgrid-yyy pattern in template's url tag has a special meaning to django? Something like "Hey python/django, if you see 'xxx-jqgrid-Entity1' in the template then don't search for the pattern in urls.py and get the list of Entity1 values from the model's table directly" ? If so, is here any documentation on how is it hooked on … -

Why does {{ user.groups }} always show auth.Group.None
When I use {{ user.groups }} in my template, I always get auth.Group.None, even though the user is logged in and is part of a group. I can access the groups from the code with request.user.groups.all(), but I need an "always works" version in my templates. -
Retrieve post variable sent via Ajax in Django
I'm processing a table of banking/statement entries that have been exported from another system via a CSV file. They are imported into a view and checked for duplicates before being presented to the user in a HTML table for final review. Once checked they are sent via AJAX to the server so they can be added into a Django model. Everything is working OK including CSRF but I cannot access the POSTed variable although I can see it! Unfortunately making a hidden form isn't viable as there are 80+ rows to process. My Javascript looks like: $.ajax({ type: 'POST', url: '......./ajax/handleImports/', data: entriesObj, success: function (data) { if (data.response && data.response) { console.log("Update was successful"); console.log(data.entries) } else { ... } }, error: function() { ... } where entriesObj is var entriesObj = JSON.stringify({ "newentries": newEntries }); console.log(entriesObj) and when dumped to console.log looks like: {"newentries":[{"Include":"","Upload ID":"0","Date":"2019-01-09", ... } Now in view.py when I return the whole request.POST object as data.entries using context['entries'] = request.POST return JsonResponse(context) I get {"{"newentries":[{"Include":"","Upload ID":"0","Date":"2019-01-09", ... } but if I try and retrieve newentries with: entries = request.POST.get('newentries', None) context['entries'] = entries return JsonResponse(context) the console.log(data.entries) will output null? How am I supposed to … -

passing an id in django homepage url

Do not redirect but show error on confirm_delete template if error occurs during DeleteView delete call
I am currently trying to override the DeleteView's inherited delete method to implement my desired behavior. However, I'm relatively new to the Django framework and Python in general and don't know what to do. The goal is to delete an object and if a ProtectedError occurs, the confirm_delete template should display an error message describing the issue and the user should not be redirected to success_url. My first approach, similar to other forms, was to pack the error into form.non_field_error, but I don't know how to access it. def delete(self, request, *args, **kwargs): self.object = self.get_object() success_url = self.get_success_url() try: self.object.delete() # Redirect to success_url except ProtectedError: pass # Add error to confirm_delete template / delete Form and stay on the delete confirmation page (don't delete) return HttpResponseRedirect(success_url) So how is it possible that the user is only redirected to success_url after a successful delete, but an error message appears on the confirm_delete template in case of a ProtectedError and no redirection takes place? -
