IMAPClient python - proper method of storing user authorization data
I am working on an email client powered by Django and IMAPClient library. On the client-side, users have interface for associating their mailboxes (like test1@gmail.com, test2@gmail.com, etc...) with their accounts in my app . And the goal is to store credentials info so that the user has to go through the procedure of inserting password and host name (like imap.gmail.com) only once unless he deliverately logs out from an account. The question is, where and how should the login/password/hostname data used for establishing IMAP connection be stored? Is it my server's DB? Or some sort of .ini files? I remember, reading a post about python/imap where they stored it in .ini files, but I can't find it now. Currently, I store credentials and IMAP hostname info in my local db. Thus, in each view that needs to fetch info from IMAP server, I query my server db to get the data and After this, I initialize IMAPClient variable for establishing connection with the IMAP server. And I have a terrible feeling that this is junk code: def show_mail(request, login): user_email_info = UserEmailInfo.objects.get(user_id = request.user.id, login = login) HOST = user_email_info.host #'imap.gmail.com' USERNAME = user_email_info.login PASSWORD = user_email_info.psw server = IMAPClient(HOST, … -
Can I simplify my django database where I have many similar views (i.e. create, list) for many different models
I have several models with similar views... Is there a way to write one list/create/detail view and apply that single view to all of my models? def modelalist(request): objects = ModelA.objects.all() context = { "objects": objects, } return render(request, "app/modelalist.html", context) def modelblist(request): objects = ModelB.objects.all() context = { "objects": objects, } return render(request, "app/modelblist.html", context) # and on and on.... What's best practice here? -

Django modelformset_factory save nothing
Created a set of forms for a simple model. When I am try to change the model object data in the form and save these changes in the database, the new data is not saved as a result, and a redirect to the form page with the same data occurs, although at least messages about the success or failure of the operation should be output. The terminal does not return any errors, it is written in the logs that the correct request was sent, the test server works without drops in normal mode. There is an opinion that the reason for this is a refusal to validate, but for what reason this happens and where exactly the error is hidden, it is not yet possible to understand. models.py (categories app) from django.db import models # Create your models here. class Category(models.Model): name = models.CharField(max_length = 30, db_index = True, unique = True, verbose_name = "Title") order = models.PositiveSmallIntegerField(default = 0, db_index = True, verbose_name = "Serial number") def __str__(self): return self.name class Meta: ordering = ["order", "name"] verbose_name = "category" verbose_name_plural = "categories" views.py (categories app) from django.views.generic.base import TemplateView from django.forms.models import modelformset_factory from django.shortcuts import redirect from django.contrib … -

Django ORM messes related objects with prefetch_related
I experience very weird behaviour of prefetch_related call. Here is the illustration: # First define two sketch models, just for convenience of the further talk. class Secondary(models.Model): pass class Primary(models.Model): secondaries = models.ManyToManyField(Secondary) # Just to make clear, EVERY Primary object in my system has at least one # related Secondary object. # Now prepare a query. primaries = Primary.objects.filter(...)\ .order_by(...)\ .prefetch_related('secondary') # Iterating: for primary in primaries: if not primary.secondaries.all(): # So we have found an object that is said to not have # any relatives. Re-query this particular object. # This part is hit in my code, although it should not. primary = Primary.objects.get(pk=primary.pk) for secondary in primary.secondaries.all(): # Voila, there are relatives! # This part was not hit for some objects until I added # the re-query part above. pass Just to make clear, there are no Primary objects in my system that do not have related Secondary objects, but still the code above hits the re-query part for some of them (always the same ones), and re-querying fetches the secondaries that were missing. And what is even more weird, I can see that some Primaries get repeating Secondaries in their secondaries.all()—the overall impression is that ORM … -

Django REST Framework JSON response on internal server error only for API calls
I'm working on a large Django app that contains a REST API through DRF on a /api/ url. I'd like to make errors respond as JSON for all views called from the API, but still respond with HTML for normal requests to all the other URLs.

Exclude a field from search results
I've got a search index defined for a model which is returning results for a given query however I'd like to specify that haystack only searches on fields exposed to the frontend. For example, the index stores the pk of the object (which is great) and if you search for a number which matches a pk you'll get that result, but the information displayed might not match that which is a little confusing if, for example, you were hoping that the place column might match the number you'd searched. Is it possible to specify a Meta attribute to the ModelSearchForm perhaps that can define fields = [] which limits what haystack uses in it's search() method? The index is defined as; class ResultsIndex(indexes.SearchIndex, indexes.Indexable): """ Results indexes for elasticsearch engine """ text = indexes.CharField(document=True, use_template=True) # Model attributes - allows for filtering etc with db hits owner = indexes.IntegerField(model_attr='owner_id', null=True) event_year = indexes.IntegerField(model_attr='event_year__id') event = indexes.CharField(model_attr='event_year__event__title') place = indexes.IntegerField(model_attr='place', null=True) def get_model(self): return Results For the frontend this is queried using the following SearchForm subclass; class ResultsSearchForm(ModelSearchForm): """ Provide additional filtering on results """ event_year = forms.ChoiceField( label=_("Event/year"), required=False, ) def __init__(self, *args, **kwargs): super(ResultsSearchForm, self).__init__(*args, **kwargs) event_year_choices = list() … -

MultipleChoiceField / CheckboxSelectMultiple values not restored on bound form

According to the docs, if I set require_all_fields to False, then I can set some fields to not be required, like this:- class MyMultiWidget(widgets.MultiWidget): def __init__(self, attrs=None): _widgets = ( widgets.TextInput(attrs=attrs), widgets.TextInput(attrs=attrs), widgets.TextInput(attrs=attrs), widgets.TextInput(attrs=attrs), ) super(MyMultiWidget, self).__init__(_widgets, attrs) def decompress(self, value): return [None, None, None, None] class MyMultiValueField(forms.MultiValueField): widget = MyMultiWidget def __init__(self, *args, **kwargs): fields = ( forms.CharField(), forms.CharField(), forms.CharField(), forms.CharField(required=False)) super(MyMultiValueField, self).__init__( require_all_fields=False, fields=fields, *args, **kwargs) def compress(self, data_list): return data_list But the HTML that this generates looks like this:- <input name="field_0" required="" class="textinput textInput form-control" id="id_field_0" autocomplete="off" type="text"> <input name="field_1" required="" class="textinput textInput form-control" id="id_field_1" type="text"> <input name="field_2" required="" class="textinput textInput form-control" id="id_field_2" type="text"> <input name="field_3" required="" class="textinput textInput form-control" id="id_field_3" type="text"> As you can see, all the fields are required. Any idea what I've done wrong here? -
How to pass data values from Views to Templates in Django?
Currently, I have two templates: no_results_tickets.html and results_tickets.html. The first template contains two drop-down menus that are used to select the year and the number of week, so once you hit the submit button, the web app looks for the tickets for the selected week and year from the Web API and then it displays the results in another Template. What I am missing right now is how to display these results in the second Template. This is what I have so far. forms.py class DropDownMenuForm(forms.Form): week = forms.ChoiceField(choices=[(x,x) for x in range (1,53)]) year = forms.ChoiceField(choices=[(x,x) for x in range (2016,2021)]) template no_results_tickets.html <h3>Please, select the year and week number to retrieve the data.</h3> <form id="search_dates" method="POST" action="/results_tickets/"> {% csrf_token %} <h6>Select year</h6> <div class="row"> <div class="col-sm-8"> <select name="select_year"> <option value = {{form.year}}></option> </select> </div> <div class="col-sm-8"> <h6>Select week</h6> <select name="select_week"> <option value= {{form.week}}></option> </select> <button type="submit">Search</button> </div> </div> </div> ulrs.py url(r'^no_results_tickets/$',views.tickets_results_test, name='no_results_tickets'), url(r'^results_tickets/$',views.tickets_results_test, name='results_tickets'), View @api_view(['GET','POST',]) def tickets_results_test(request): if request.method == "GET": ''' Template for displaying the dropdown menus.''' template_name = 'personal_website/no_results_tickets.html' form = DropDownMenuForm() return render(request, template_name, {'form': form}) elif request.method == "POST": template_name = 'personal_website/results_tickets.html' year = request.POST.get('select_year', None) week = request.POST.get('select_week', None) # ... do …
