Module 'django.db.models' has no attribute 'FileBrowseField' - django

Question

I would like to have on my Django 2.1.1 site django-filebrowser-no-grappelli. I've followed this indications but at the end of the procedure, when I restart my server, I've this error:
header_image = models.FileBrowseField("Image", max_length=200,
directory="images/", extensions=[".jpg"], blank=True) AttributeError:
module 'django.db.models' has no attribute 'FileBrowseField'
This are the files of my project:
MODELS.PY
from django.db import models
from django.urls import reverse
from tinymce import HTMLField
from filebrowser.fields import FileBrowseField
class Post(models.Model):
"""definizione delle caratteristiche di un post"""
title = models.CharField(max_length=70, help_text="Write post title here. The title must be have max 70 characters", verbose_name="Titolo", unique=True)
short_description = models.TextField(max_length=200, help_text="Write a post short description here. The description must be have max 200 characters", verbose_name="Breve descrizione dell'articolo")
contents = HTMLField(help_text="Write your post here", verbose_name="Contenuti")
publishing_date = models.DateTimeField(verbose_name="Data di pubblicazione")
updating_date = models.DateTimeField(auto_now=True, verbose_name="Data di aggiornamento")
header_image = models.FileBrowseField("Image", max_length=200, directory="images/", extensions=[".jpg"], blank=True)
slug = models.SlugField(verbose_name="Slug", unique="True", help_text="Slug is a field in autocomplete mode, but if you want you can modify its contents")
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse("singlearticleView", kwargs={"slug": self.slug})
class Meta:
verbose_name = "Articolo"
verbose_name_plural = "Articoli"
VIEWS.PY
from django.shortcuts import render
from .models import Post
from django.views.generic.detail import DetailView
from django.views.generic.list import ListView
class SingleArticle(DetailView):
model = Post
template_name = "single_article.html"
class ListArticles(ListView):
model = Post
template_name = "list_articles.html"
def get_queryset(self):
return Post.objects.order_by('-publishing_date')
URLS.PY
from django.urls import path
from .views import ListArticles, SingleArticle
urlpatterns = [
path("", ListArticles.as_view(), name="listarticlesView"),
path("<slug:slug>/", SingleArticle.as_view(), name="singlearticleView"),
]
ADMIN.PY
from django.contrib import admin
from .models import Post
class PostAdmin(admin.ModelAdmin):
"""creazione delle caratteristiche dei post leggibili nel pannello di amministrazione"""
list_display = ["title", "publishing_date", "updating_date", "id"]
list_filter = ["publishing_date"]
search_fields = ["title", "short_description", "contents"]
prepopulated_fields = {"slug": ("title",)}
fieldsets = [
(None, {"fields": ["title", "slug"]}),
("Contenuti", {"fields": ["short_description", "contents"]}),
("Riferimenti", {"fields": ["publishing_date"]}),
]
class Meta:
model = Post
admin.site.register(Post, PostAdmin)
URLS.PY PROJECT
from django.contrib import admin
from django.urls import path, include
from filebrowser.sites import site
urlpatterns = [
path('admin/filebrowser/', site.urls),
path('grappelli/', include('grappelli.urls')),
path('admin/', admin.site.urls),
path('', include('app4test.urls')),
path('tinymce/', include('tinymce.urls')),
]
I've started all of this because I will use TinyMCE and a file browser application is necessary. When I deactive the string header_image in models.py the project running well but, obviously, when I try to upload an image I've an error.
Where I made a mistake?

Answer 1

your import is done like this:
from filebrowser.fields import FileBrowseField
but you're trying to use the field following way:
header_image = models.FileBrowseField(...)
It's not part of the models package, just do it without the models. part:
header_image = FileBrowseField(...)
