Customizing django admin panel
So I have a very simple and new Django site up and running, and I'm really wanting to customize the look of the admin panel. I would basically like it to extend from my base.html. I have read the docs on Overriding admin templates but it hasn't quite answered my question as I don't believe the file I am looking for (base.html) is listed in their files that you're able to override. I've done the only thing I had in mind which was copying the templates/admin/base.html and pasting it in my own templates/admin directory, extending my base, and removing their header sadly this is what I got from that, which is close but not really. -

Submiting a form using JavaScript in Django is not working
I try to submit a form by Javascript in Django. The form is working The Javascript is working The submit() function is not working. My testing HTML code: <form method="post" id='testForm' action="www.google.com"> {% csrf_token %} <a onclick="onDeleteButtonClick()" href="">Delete</a> <input type="submit" value="Submit"> </form> My testing Javascript code: <script type="text/javascript"> function onDeleteButtonClick(){ console.log("before"); document.getElementById("testForm").submit(); console.log("after"); } </script> 3 Results: This part of the web page looks like this: enter image description here Really simple A When I click the Submit button: It is working, the form is been submit. B When I click the delete link: It is not working. The log in Javascript works, I can see "before" and "after" in the console. C I also test this on a normal web page (without Django framework), the Submit button, and the Delete link is all working. So I think it must be something related to Django. If anyone knows why this happened, please let me know~ Thank you! -

Docker can't open file to run the python application in a container with django using docker-compose
I'm new to Django. I want to run the code of the example at https://github.com/wsvincent/djangoforprofessionals/tree/master/ch1-hello.

Django Apache configuration stati files
I've a little issue about the configuration of Django and Apache on AWS Lightsail. I followed this guide: https://aws.amazon.com/it/getting-started/hands-on/deploy-python-application/ point 5) Host the application using Apache I configured all the files just like this guide (obviously using the name of my prj instead of "template") It's working everything, except the static files: I mean, I just see my website without any css/img/js.. Have I add something in urls.py? in settings.py? I tried everything... How can I configure correctly Apache? For me it's the first time dealing with Django and Apache, and I cannot find a guide that works for my situation. This is my tree of the prj: tree-prj-img Thank you, Manuel -

Why is my Query not working? 'Exception Value: Cannot use QuerySet for "Conversation": Use a QuerySet for "Profile" '
I am attempting to query Conversation, which has a many to many field called members. I am doing this so that I can then pass Conversation to my InstantMessage object because that object has a foreign key called conversation that attaches to Conversation. I need to check if members are apart of Conversation first, and then if so, get, or if not, create, and then pass that into my InstantMessage object.

Python framework for CLI development
Need to write python CLI scripts - basic functionalities include - expose REST APIs, consume REST APIs, connect to Oracle/sql-server etc.Hooking onto a front end is not an immediate requirement - but its a possibility. Checked here, here etc. - came to realize that there is no file structure which is universally accepted. Checked various frameworks like click, cement, django, flask etc. - kind of decided on django(as may need to hook a front-end later in time).Here are my concerns: Is it an overkill to use django for CLI development Do we get all features of django(like ORM etc.) if we choose to run from CLI(without web server) If I start with click(for example), how difficult will it be to hook front end in future Please advice. -
Checking if user exists in django table once when looping through values
I have a table where I query all the objects into 'test' in views def book_module(request): test = books.objects.all() and in html, I'm trying to check whether user exists once inside of it. The issue I'm running into is that it is instead printing out every time it finds it inside the table.. table example user col1 col2 col3 test 1 1 1 test 1 1 1 test_2 1 1 Here is my html code.

Set default value to reference own relationship in django migrations
I am updating a Picture model to add additional information and need to set some default values. When the migration runs, I want to populate the DB with some reasonable default values which can be obtained from the user within it. These are my models: class User(models.Model): ... company = ForeignKey(Company, on_delete=models.CASCADE) ... class Picture(models.Model): ... user = ForeignKey(User, on_delete=models.CASCADE) company = ForeignKey(Company, on_delete=models.CASCADE) # New field being added ... The Picture would belong to a company even if the user changes companies. When making migrations, Django wants to know a default value for the company field on Pictures. Is there a way to tell it to look at the Pictures user and use the company that user has? -
Nginx caching of uwsgi served static files
The django project is deployed using uwsgi as application server, it also serves static files from a specified directory(as shown in the below command) and nginx is used as reverse proxy server. This is deployed using docker. The uwsgi command to run the server is as follows: uwsgi -b 65535 --socket :4000 --workers 100 --cpu-affinity 1 --module wui.wsgi --py-autoreload 1 --static-map /static=/project/static; The application is working fine at this point. I would like to cache the static files into nginx server. So i have referred blog https://www.nginx.com/blog/maximizing-python-performance-with-nginx-parti-web-serving-and-caching and i have included following configuration in my nginx.conf : location ~* .(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|css|rss|atom|js|jpg |jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid |midi|wav|bmp|rtf)$ { expires max; log_not_found off; access_log off; } After adding this into my Nginx conf, the Nginx server container exits with the following error: [emerg] 1#1: invalid number of arguments in "location" directive in /etc/nginx/nginx.conf:43 Is this how uwsgi served static files can be cached into nginx? If yes please suggest me what is gone wrong here.

Django validate_unique method all ready exists message
Thinking How to get the instance pk that exists during validate_unique? it is not a good practice to overwrite the method validate_unique and I don't know if it would be correct to validate unique fields in the clean() method. but imagine the following situation: you want to show admin users which is the instance that already exists so they can edit it if they want, I think it would be more intuitive when working with thousands of data. the following code is just an example - think about it as a pseudocode although I tried it and it works, I know it could be better def clean(self): lockup ={} unique_togethers = self._meta.unique_together[0]#these could throw an error for field in unique_togethers: f = self._meta.get_field(field) value = getattr(self, f.attname) if value is None: continue if f.primary_key and not self._state.adding: continue lockup[str(field)] = value qs = snippet.objects.filter(**lockup) if qs.exists and self._state.adding: raise ValidationError( format_html('''this object all ready exist plese edit it on <a href="{}">Edit</a>''', reverse('admin:testing_snippet_change', args=(qs[0].pk,)))) Is this approach correct, how to apply it to the validation_unique method to works in all unique validations?

Why form.is_valid() does not returns false immediately when the first clean_<field_name> raises ValidationError?
I have defined a form with two CharField. I have defined clean method for both fields. In my view i am calling is_valid() method of the form I defined. I am giving an invalid input for field1 so that clean_field1 method raises ValidationError. In clean_field2 i am accessing cleaned_data[field1]. When calling the url, it is giving 500 error. And in stack trace it says KeyError: 'field1'. On debugging I found ValidationError was raised in clean_field1 method. I expected that form.is_valid() will return false when clean_field1 raised ValidationError. But django went on to execute clean_field2. Why django is executing clean_field2, when clean_field1 raised ValidationError. form.is_valid() should have returned false when clean_field1 raised ValidationError. Am I correct? Does Form.is_valid() method return only after executing all clean_<'field_name'> methods(even if ValidationError was raised)? If yes, then this poor design I think. If first clean_<'field_name'> method raises ValidationError then what is the point in executing other clean_<'field_name'> method? I think Form.is_valid() should return false when it encounters first ValidationError. Or am I missing something? It will be really helpful if anyone can explain what is going on? Thank you. The code that I was executing: class MyForm(Form): field1 = forms.CharField() field2 = forms.CharField() def clean_field1(self): … -
Django queryset get empty values in query
So I'm trying to get all the values to be able to display in my templates. However I have encountered myself with this problem: I have these models: class Project(models.Model): projectId = models.AutoField(primary_key=True, db_column="Id", db_index=True, verbose_name='Project ID') description = models.CharField(max_length=900) class PM(models.Model): PMid = models.AutoField(primary_key=True, db_column="Id", db_index=True) PMNumber = models.CharField(max_length=50, unique=True, db_column="PMNumber") description = models.CharField(max_length=600) projectId = models.ForeignKey(Project, on_delete=models.CASCADE, db_column="ProjectID", related_name='+') And I'm trying to get all the projects with their respective PMNumber. For which I'm trying something like this: fpm = PM.objects.all() projects = [] for i in fpm: projects.append('ProjectName': i.projectId.description, 'PMNumber': i.PMNumber}) After that the result is like this [{'ProjectName': 'pr1', 'PMNumber': '119508-01'}, {'ProjectName': 'pr1', 'PMNumber': '119490-01'}] However, I'm still missing some projects that don't have a PM related to them, I want all the projects in the queryset to be able to show them in a template, not just the ones that have a PM. It should look something like this: [{'ProjectName': 'pr2', 'PMNumber':'None'}, {'ProjectName':'pr3' , 'PMNumber':'None'}, {'ProjectName': 'pr1', 'PMNumber': '119508-01'}, {'ProjectName': 'pr1', 'PMNumber': '119490-01'}] Is there a way to do this? or is there another way to do this in the views?
