Cannot open a bootstrap navbar on django
I'm asking this question in hopes that I ask it better this time. My bootstrap 4 navigation bar on my home page (Album template) does not click open and dsiplay links. Here is picture of what happens when I try to load this page in django. Those three lines cannot be clicked and opened. This is what should happen when those three lines are clicked. I've properly uploaded the boostrap album.min.css and the page loads and looks just like the original album example. I've also uploaded the stylesheet for this page. It looks exactly like the album example, except the navbar link cannot be clicked. Everything else works fine. My static files load. Here is the html file. {% load staticfiles %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <meta name="description" content=""> <meta name="author" content=""> <link rel="icon" href="../../favicon.ico"> <title>Album example for Bootstrap</title> <link href="{% static 'css/album.min.css' %}" rel="stylesheet"> <!-- Custom styles for this template --> <link href="{% static 'css/album.css' %}" rel="stylesheet"> <!-- jQuery (necessary for Bootstrap's JavaScript plugins)--> <script href="{% static 'js/jquery.js' %}" ></script> <!--jquery--> <!-- <script href = "{% static 'js/collapse.js' %}"></script> <script href = "{% static 'js/dropdown.js' %}"></script> --> </head> <body> <div class="collapse … -
Django - Hod do I request cURL from views
I am beginner to Django.

django login_required for variable urls
I am trying to write a basic website in django. I need the user (i'm still using the default one) to be able to login, logout, register, etc. I have the basic functionality set up, but I want the user to be able to visit a profile page where it will display basic information about the user. Naturally, the profile page must use the login_required decorator but the way I have it set up now is that once anybody signs in they can see any profile page. Part of the URL file: url(r'^profile/(?P<username>[\w.@+-]+)/$', login_required(ProfilePageView.as_view())), As you can see, the url should consist of "profile/" follow by the username of the user. How can I set it up so that only the user with the username following the "profile/" part of the url can see that page. With this code some user could login with any username and then just change the url and resend the get request. -
Django Image by Foreign Key and {% if / else %}

I have different Animal Apps in my Projects, with almost the same structure, like the following models.py.

rjust() inside __str__() not working in Django
I have a model class with level and name fields (it's about subcategories levels). I want to display the name of each row with corresponding number of dashes indent in the select dropdown in the admin panel. When I use: def __str__(self): return self.name.rjust((self.level-1) * 4, '-') in the Django model, it doesn't work and keeps showing me the name without the dashes. If I use the same code in a pure Python script, it does work. Debug showed that self.level has correct value in the __str__() Django function. Why it doesn't work in Django and how to fix it? -

How can one create a custom "as_table()" method for forms?
I have a relatively complicated form that's used in multiple places on my website (in fact, it's a form from which many other form classes inherit). The inherited part of this form is always formatted identically—but that formatting is somehwat involved; each field is rendered and positioned manually in the template. This means that every template which displays this form has a lot of identical HTML markup that renders the form appropriately. I would like to create a custom output that can be called, similar to the as_table() methods. I'm aware that one can override the normal_row, error_row, etc. attributes—but the formatting of this form goes beyond that (for example, three of the form's five fields should be printed side-by-side, with a combined title). All of the tutorials/answered-questions I've seen either refer to overriding the above-mentioned attributes, or give instructions on how to manually render forms. Originally, I was thinking something like this: Class StrangeForm(form.Forms): .... def as_table_custom(): html_string = "\ <tr><td>Title 1:</td><td>self.fields['field1']</td><tr>\ <tr><td>Title 2:</td><td>self.fields['field2']</td><tr>\ <tr><td>Titles 3, 4, 5:</td><td>self.fields['field3']\ </td><td>self.fields['field4']</td><td>self.fields['field5']</td></tr>\ " return html_string But, after reading through the _html_output() and as_table() methods of Django's forms.py file, it doesn't look like it'll be that easy. If I write this from scratch, … -

Django - How do I display only the questions with choices?
I am completing the official Django tutorial. The tutorial involves creating a polls app, which consists of creating questions with choices. Currently, the index page shows one question instance for each choice that the question has. For example, if the question is 'what is your favourite thing to eat?' and that question's choices are 'Cabbage', 'Metal', and 'My pride', the index page shows three repetitions of 'what is your favourite thing to eat?'. I am trying to alter the index page to display only one instance of each question that has choices. How must I change what I have written already? views.py class IndexView(generic.ListView): template_name = 'polls/index.html' context_object_name = 'latest_questions' def get_queryset(self): """ Return the last ten published questions.

How to set the initial value for different relationship fields in Django's admin
Summary We would like to set the initial selection of the select-boxes representing different kinds of model relationships on a basic "add" or "change" page in the Django admin. The initial selection should be saved to the database, if the user clicks one of the "Save" buttons. We specifically want to do this by setting the initial value on the form fields (for ModelAdmin or TabularInline). The question is: What is the proper "value" to assign to Field.initial, for different kinds of relationship form-fields? Background Suppose we have a simple Model with one or more relationship fields, i.e. OneToOneField, ForeignKey, or ManyToManyField. By default, the latter has an implicit through model, but it may also use an explicit through model, as explained in the docs. An explicit through model is a model with at least two ForeignKey fields. The relationship fields, represented by select-boxes, appear automatically on the standard ModelAdmin "add" or "change" forms, except for the ManyToManyField with explicit through model. That one requires an inline, such as the TabularInline, as explained here in the docs. Goal Now consider a basic Django ModelAdmin "add" (or "change") page for this model, including inlines for any explicit through models. We want … -

Django forms - best practice to set initial values in __init__() method
Sorry if this is a broad question, but I am trying to understand the best practice way to set initial values, edit fields (make readonly for E.g) in a django form init() method. Take my form for instance: class ResultForm(forms.ModelForm): evidence = forms.CharField( widget=forms.Textarea(attrs={'rows': 3, 'cols': 60}), label='Evidence:', required=False, ) def __init__(self, *args, **kwargs): super(ResultForm, self).__init__(*args, **kwargs) result_obj = self.instance if result_obj.tier_id: self.fields['evidence'].widget.attrs['readonly'] = True self.fields['evidence'].widget.attrs['class'] = 'classified' else: ... do stuff ... self.initial['evidence'] = new_evidence_variable class Meta: model = Result fields = ( 'id', 'evidence', 'tier_id', ) This is fine to render the unbound form, however when I attempt to validate it with POST data, the init method is run without a proper instance, and it fails. My way around this, is putting my code in init in a try/except block: class ResultForm(forms.ModelForm): evidence = forms.CharField( widget=forms.Textarea(attrs={'rows': 3, 'cols': 60}), label='Evidence:', required=False, ) def __init__(self, *args, **kwargs): super(ResultForm, self).__init__(*args, **kwargs) try: result_obj = self.instance if result_obj.tier_id: self.fields['evidence'].widget.attrs['readonly'] = True self.fields['evidence'].widget.attrs['class'] = 'classified' else: ... do stuff ... self.initial['evidence'] = new_evidence_variable except: pass class Meta: model = Result fields = ( 'id', 'evidence', 'tier_id', ) This seems to work, however it seems a little hacky. Is there a 'better' or … -

I am already using Q: length_filter = Q(length__lt=5000) unread_articles = Article.objects.filter(length_filter).all() How to I extend this to exclude all articles whose ID/User combination are in the read_articles table?
