Upload webscrapped images from folder to database Django
I'm webscrapping data about ski resorts from a site, also getting some pictures. I am saving those pictures in a folder and after that i'm getting them in SQLite database through an imageField. The bad part is that they don't work directory = r'C:\Users\tiberiu.ghimbas\Documents\Resorts img5' image_list = [cv2.imread(file) for file in glob.glob(r'C:/Users/tiberiu.ghimbas/Documents/Resorts img5/*.png')] This list is then looped and insertet item by item. I'm doing all the correct settings for handling images and media files. I know that by going the classic way of uploading images through a form will get you in the database the path to the image from de media/"upload_to = 'filename'" folder but going by my way i'm getting only them image name. How can i solve that ? -

Can I Extend My Template Based on a Condition -Django
I have a template that needs to use separate base templates depending on whether a user is a system admin or a regular administrator. The main difference between the two templates is that one contains more nav bar items and links to other portions of the app. I'd like the system to recognize whether a user is a system admin or regular admin and extend the correct base template off of that test. I know this can be accomplished by creating a second template and doing something like this in the views.py file: if sysAdmin == True: template = loader.get_template('app/template1.html') else: template = loader.get_template('app/template2.html') There are multiple shared views between the two user groups and I would rather not have 4 sets of templates that are almost completely identical. I'd prefer to do something like: {% if sysAdmin == True %} {% extends "app/sysAdminBase.html" %} {% elif sysAdmin == False %} {% extends "app/adminbase.html" %} {% end if %} However, this throws the error Invalid block tag on line 3: 'elif'. Did you forget to register or load this tag? Is this possible or will I need to create duplicate templates? Thank you -

Index a foreign key in Django Models
I want to index a very common query in a project that involves a CharField and ForeignKey. I have a bottleneck with this query and I am trying to optimize it. I have this: class Bill(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) category = models.CharField(max_length=200, null=True, blank=True) ... I added this to try to improve the performance: class Meta: indexes = [ models.Index(fields=['category', 'company']), ] But the result is the same, the query is: models.Bill.objects.filter(company=company, category='recibida') Is there something else that I could improve? Is this indexing well done? -
Why is Django not picking up my admin override?
I'm trying to override the Django admin's index method for my api project, following the guide here. In api/admin.py, I have class ApiAdminSite(admin.AdminSite): def index(self, request, extra_context=None): raise Exception('to see if I am even being called') # I remove this when satisfied .... admin_site = ApiAdminSite() admin_site.register(MaxImpactFundGrant, MaxImpactFundGrantAdmin) admin_site.register(Evaluation, EvaluationAdmin) # and other model registrations In api/apps.py, I have from django.apps import AppConfig from django.contrib.admin.apps import AdminConfig class ApiConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'api' class ApiAdminConfig(AdminConfig): default_site = 'api.admin.ApiAdminSite' In api/../settings.py, aka the folder above my app, aka not the settings file the guide specifies, I have INSTALLED_APPS = [ 'api.apps.ApiConfig', 'modeltranslation', 'api.apps.ApiAdminConfig', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ] And when I load the admin index page, it loads ok, but just hasn't registered any of my models: So maybe I've got the wrong settings.py? But I've tried creating one in the api folder and adding just that list to it, and nothing changed. I also tried editing the top level urls.py file to specify the new admin, though I had to hack it to give the new admin a 'site' attribute: from django.urls import path, include from django.contrib import admin from api.admin import admin_site admin_site.site = admin.site urlpatterns … -

If fetch returns object with multiple attributes (ie. object.exists and object.message) how can I use them after fetch is done?
After fetch returns object it logs it perfectly and I can see all attributes in the object. I can even change the html in the page using all the attributes. login_button=document.getElementById('submit-login'); login_form=document.getElementById('login-form'); message=document.getElementById('message'); login_button.addEventListener('click',async (e)=> { e.preventDefault(); form=new FormData(login_form); let response = await fetch('/',{ method:'POST', body: form, headers:{ 'X-CSRFToken':document.cookie, // 'X-Requested-With': 'XMLHttpRequest', }, }); let processed_response=await response.json(); console.log(processed_response); if (processed_response.exists){ console.log('success'); message.classList.remove('failure'); message.classList.add('success'); } else{ message.classList.remove('success'); message.classList.add('failure'); } message.firstElementChild.innerHTML=processed_response.message; setTimeout((processed_response) => { window.location=processed_response.next; },1000); }); However, when I try using the setTimeout function it logs the following: Uncaught TypeError: can't access property "next", processed_response is undefined And well I'm not able to use the attribute from the object in the setTimeout function. Is there something I'm missing. This is my first time dealing with async and fetch/promises so sorry for any low quality code here. Thanks in advance. -

how to disable User fields to show my custom form in my template?
I have a problem with a form. It is a form that works like an "edit profile". I just want to style it, I don't like how it looks if I just put {{ form }} in my template, I'm using widget_tweaks to give it a better look. The problem is that when I use widget_tweaks and click the "Save" button, it doesn't work. But if I use the unstyled form {{ form }} instead, it does edit the fields. I'm thinking that when rendering the fields with widget_tweaks I'm not including the default User fields like: password, last login, etc. because I don't need them, I think that is influencing my form not working. Do you have any idea how to disable the default User fields and can I use the widget_tweaks or is it better to use forms.py? models.py COUNTRIES=( ('EUA', ('EUA')), ('Canada', ('Canada')), ('Other', ('Other')), ) class CustomUser(AbstractUser): phone1=models.IntegerField(default=0) phone2=models.IntegerField(default=0) fax=models.IntegerField(default=0) website=models.CharField(max_length=100,default=0) socialMedia1=models.CharField(max_length=100,default=0) socialMedia2=models.CharField(max_length=100,default=0) socialMedia3 = models.CharField(max_length=100,default=0) alternativeContact=models.CharField(max_length=100,default=0) country = models.CharField(max_length=100, default=0,choices=COUNTRIES) address=models.CharField(max_length=100, default=0) city=models.CharField(max_length=100,default=0) state=models.CharField(max_length=100,default=0) zip=models.CharField(max_length=10,default=0) tax_percentage=models.IntegerField(default=0) def __str__(self): return self.phone1 admin.py # Register your models here. class CustomUserAdmin(UserAdmin): add_form = UserCreationForm form=UserChangeForm model=CustomUser list_display = ['pk','email','username','first_name','last_name'] add_fieldsets = UserAdmin.add_fieldsets+( (None,{'fields':('email','first_name','last_name','image','location','phone1','phone2','fax','website', 'socialMedia1','socialMedia2','socialMedia3','alternativeContact','country','address', 'city','state','zip','tax_percentage')}), ) fieldsets = … -

Path finding between models in Django
I am trying to make a graph like structure in django using models to create paths between model instances. But I am no quite sure about how to do that automatically. The basic structure of my models is something like this: class Location(TimeStampedModel): name = models.Charfield() level = models.SmallPositiveIntegerField() previous_locations = models.ForeignKey('self') next_locations = models.ForeignKey('self') related_locations = models.ForeignKey('self') That previous_locations, next_locations and related_locations were my first approach in order to get some kind of tree structure, but they are pretty useless when there are several locations with the same level. For example, location_1 (with level = 1) can go to location_2 and location_3 (both with level = 2) and then both can go to location_4 (with level = 4). Maybe changing the foreign key to a many to many relation can solve this, but it's still not clear to my how to create the paths. For the paths, I made the following model: class Path(TimeStampedModel): name = models.Charfield() locations = models.ManyToManyField(Locations) Summarizing, the goal is select two locations and automatically create the shortest path or a group of paths (as maybe 2 paths require the same amount of steps). However, I don't know how to doit with the relations I …
