Where should authentication backends reside in a django project structure
I am setting up UAM interface to bypass default Django authentication. My question is how to place the new Backend Class in the directory structure Following is my project structure: django-app-folder - appmodule1 - appmodule2 - appmodule3 - utils - management - migrations - tests - static - templates - apps.py - admin.py - models.py - signals.py - urls.py - views.py django-soln-folder - settings.py - urls.py - wsgi.py -
The for loop variable in the for loop
I want to use the value from one for loop in another for loop. But I have 3 values in the tables variable in the context dictionary from views.py. I want to pull these values with the for loop and return them with another for loop, but the 2nd for loop sees the value from the 1st for loop as a string. {% for table in tables %} {% for music in table %} <a class="{{table}}" href="javascript:void(0);" onclick="playSong('{{music}}')">{{music}}</a> {% endfor %} {% endfor %} In Page Source : <a class="Rap" href="javascript:void(0);" onclick="playSong('R')">R</a> <a class="Rap" href="javascript:void(0);" onclick="playSong('a')">a</a> <a class="Rap" href="javascript:void(0);" onclick="playSong('p')">p</a> I want the values in the rap table, not the outputs like R, a, p in the a tag. 2. The for loop sees this as a string, but in my context dictionary there is the Rap keyword and its values. I want to draw the values of this keyword. -
Django 2 upgrade lost filter_horizontal functionality
I recently upgraded to Django 2.2.2 and Python 3.6.8, and my filter_horizontal feature in Django admin has disappeared. I tried viewing my admin in Chrome incognito mode, as some answers suggest, and I also tried changing verbose_name strings to unicode. However, none of these worked. Here is an example of a model for which I am attempting to show filter_horizontal. This worked on my app prior to the upgrades. admin.py class ResearchAdmin(admin.ModelAdmin): filter_horizontal = ('criteria', 'state') def save_model(self, request, obj, form, change): obj.save() # Update cache for tasks containing the saved goal tasks = Task.objects.filter(research__id=obj.pk).values_list('pk', flat=True) for t in tasks: cache.delete_many(['task%s' % t, 'task%s_research' % t]) models.py """ Clinical Research model """ def __str__(self): return "%s" % (self.name) name = models.CharField(max_length=50, null=True, blank=True) type = models.CharField(max_length=50, null=True, blank=True) cta = models.CharField(max_length=50, null=True, blank=True) description = models.TextField(null=True, blank=True) picture = models.ImageField(upload_to='images/%Y/%m/%d', null=True, blank=True, help_text="Upload portrait image for modal study description") layout = models.CharField(max_length=1, choices=LAYOUT_TYPE, null=False, blank=False, default='r') criteria = models.ManyToManyField('Answer', blank=True, db_index=True, help_text="Answers required for qualified patients") required_contact = models.ManyToManyField('ContactField', blank=True, db_index=True, help_text="Contact info for patient to enter") email = models.EmailField(null=True, blank=True, help_text="Sponsor email for notifying of screened patients") link = models.URLField(null=True, blank=True) state = models.ManyToManyField('State', blank=True, help_text="Qualifying states") lat = … -
Applying Django migrations once per deployment application in Kubernetes/Google CloudSQL
I'm looking for a robust and reliable strategy to apply my database migrations once per application of my Deployment yaml file to use in my CI/CD pipeline. The initial (no pun intended) plan was to use initContainers to perform the migration. The difficulty I'm encountering has to do with the method of connecting to the CloudSQL database--since I'm using the gcr.io/cloudsql-docker/gce-proxy:1.11 sidecar container to let my application containers connect, I'm not sure how to provide the database access to the initContainers because they appear to only support single containers pods. Is it possible to run the proxy container as a sidecar on the initContainers? If that is not possible, what is the preferred approach? Should the entrypoint of the application containers apply the migrations before launching the application itself? My concern is that in an initial launch of the deployments might create race conditions with multiple pods trying to apply migrations simultaneously? -
Get values from Django data base
I need to get the data from a form in a Django database. The problem when I use .cleaned_data['name'] I am getting an attribute error 'SnippetForm' object has no attribute 'cleaned_data'. when I tried passing through if old_form.is_valid(). the if is False. With my code, I can get the HTML info, but I can not parser it with .clean_data. Basically I don't want to create a regex and parse the html, I am looking for some Django Method that can help.

How to Go From 1+n to 1+1 Requests
I have a RESTful API request which returns upwards of 1,000 records in the form of JSON data. From this data I pull an ID to reference in a second API request to a different domain. The current logic results in slow page load times due to the large number of records being iterated through. How can I increase page availability and decrease wait times? Is there any way I can transition to 1+1 requests instead of 1+n? views.py cw_presales_engineers = [] for opportunity in opportunities: try: opportunity_id = str(opportunity['id']) presales_ticket = cwObj.get_tickets_by_opportunity(opportunity_id) if presales_ticket: try: cw_engineer = presales_ticket[0]['owner']['name'] cw_presales_engineers.append(cw_engineer) except: pass else: cw_engineer = '' cw_presales_engineers.append(cw_engineer) except AttributeError: cw_engineer = '' first.request def get_opportunities(self): try: r = requests.get( self.URL + 'sales/opportunities?conditions=status/id=1 OR status/id=13 AND company/name!="XYZ Test Company" &pageSize=50& &oage=1& &orderBy=company/name asc&', headers=self.Header) r.raise_for_status() except: raise return r.json() second.request def get_tickets_by_opportunity(self, request): try: r = requests.get( self.URL + 'service/tickets?conditions=opportunity/id=' + request, headers=self.Header) r.raise_for_status() except: raise return r.json() -
Creating Admin List filters for custom list_display functions?
Is it possible to create list_filters on the admin model page based on a function created to pull info on models that are a couple of Foreign Keys away? I've created the functions to display the info needed in 'list_display', but am hoping to also be able to filter using these fields. The current admin.ModelAdmin functions are seen here: class HardwareAdmin(admin.ModelAdmin): list_display = ('hardware_id', 'device_type', 'get_customer', 'network_health','get_region') def get_customer(self, obj): if obj.site: return obj.site.customer return '-' get_customer.short_description = 'Customer' get_customer.admin_order_field = 'site__customer' def get_region(self, obj): if obj.pad: return obj.pad.lease.region return '-' get_region.short_description = 'Region' How would I go about adding filters that allow me to filter by both region and customer? -

Two identical PNGs, one is corrupt
I have this PNG file, uploaded to a django REST server from an Angular front-end. About 99.9% of uploaded images work fine; you can view them in admin and download them. But every once in a while, I get these corrupt PNG images. You can see the image if you put the image URL in the address bar but you can't see it on django admin and you can't download it through right click>save. I uploaded and downloaded the image to Imgur and now it seems to be working. When I put it in the media directory of the Django development server, I can download it with the right click at the image URL. But it seems to be identical to the original file! I get nothing with a diff File sizes are the same Neither of the files seem to be open (checked with lsof) I'm out of options. I uploaded both versions of the images to my google drive and checked that if you download the images, corrupt one still seems to be corrupt. Maybe somebody can figure out what the difference between these files is. corrupt image saved and fixed image -

How to hide tracebacks for users when an import csv fail using django import export library

How do I properly provide user field to ModelSerializer in Django Rest Framwork
I have a django Profile model as: class Profile(models.Model): created_by = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=100, blank=True) meta = models.TextField(blank=True) def __str__(self): return self.created_by And a serializer (which I know is not currently doing much) class ProfileSerializer(serializers.ModelSerializer): class Meta: model = Profile fields = '__all__' In my update method in view, I can't ever seem to validate the serializers. This is how I am going about it: profile = Profile() profile.created_by = request.user serializer = ProfileSerializer(profile) serializer.is_valid() always returns False. And by the way, request.user is an authenticated CustomUser. I have also tried setting serializer = ProfileSerializer( instance=profile, data={'created_by':request.user} ) And many combinations thereof. What am I missing that the serializer can't be validated? Clearly there's some trouble with the user here. Extra: I am new to DRF, why is the 'created_by' field set by default when DRF seems to know who the user is? -

Generate separate translation files with django-admin
How I can generate separate *.po files for my Django project? This files used only for automatic database table fill. Table look's like: id | SKU | en | cz | ... I need only SKU and lang column to generate filter dropdown for the user. Command django-admin makemessages -a includes them to the one main file. There are large dataset with 2000+ entries in summary. So I want to split them into the parts. Especially, because most of them used only during table fill. I have tried pygettext.py command, but it doesnt generate *.po files for all website locales. And this command removes already translated content. -

Simple solutions to create an interface with a python script?
I coded a simple Python script to automate some accounting work at my internship and it has worked wonderfully. However, now that I am leaving I am a bit worried about the other accountants being able to use the same script from the command line or JupyterLab. It would be amazing if I could create a simple interface for them so they don't have to learn anything new (: the script is really simple: it imports an excel file from the user's computer, transforms into a data frame, replaces a few strings, does some calculations, deletes some columns, and outputs an excel file with the new formatting. The script can be viewed at my github here: https://github.com/brunnatorino/FEC/blob/master/ALL_app.py I even tried adding some user input functions so they wouldn't have to mess with the code, but that has also proven challenging for them to learn and remember. Is there any simple interface solutions where I can use my existing script? I would prefer to have the least amount of modifications to the code as I don't have a lot of time left in my internship. -
