ImportError: No module named 'datasets' while integrating with django
I'm trying to integrate inception_v3 inside my django app. I have cloned the repository https://github.com/tensorflow/models inside my django app. I have made a file test.py in which i'm importing the following: from .models.research.slim.datasets import dataset_utils when i'm running test.py from my terminal, i'm getting the desired output, but when running the command of runserver django is giving me error of ImportError: No module named 'datasets' the dataset folder is inside "models/research/slim" and the test.py file as well as the models folder are within my django app. website/myapp/test.py, models i'm using a ubuntu 16.04 OS with python3.5 -
Encoding Japanese/International characters on IIS7.5 with wfastcgi and Django website
I have a Django website set up with IIS7.5 and wfastcgi. Some of the data saved to the models is in Japanese. Everything works fine when locally using Django's runserver, but when using the IIS setup the Japanese characters are incorrectly encoded. For example, on the Django admin page when I try to edit the existing data with Japanese characters "test3種別" in one of the models I get the message: with ID "test3%8E%ED%95%CA" doesn't exist. Perhaps it was deleted? "test3%8E%ED%95%CA" is "test3種別" in Shift-JIS encoding. The database (sqlite3) is being searched for the correct id, wrongly encoded. I have set the web.config file to include <globalization fileEncoding="shift_jis" requestEncoding="utf-8" responseEncoding="utf-8" culture="ja-JP" uiCulture="ja-JP" /> but this hasn't fixed the problem. I've looked around for a solution with not much luck. Does anyone know how to solve this problem? Any help would be appreciated. -
Redis Server: "Cannot import BACKEND %r specified for %s"

Django URL using javascript to get client end information
My problem that I am trying to resolve is that I made an Ajax-autocorrect input feature and "onclick" of a button I get the value inside that input and attempt to make the page redirect to a Django URL. Here is the URL inside my url.py file: url(r'^groups/add-member/(?:/(?P<pk_group>[-\w]+))?/(?:/(?P<pk_member>[-\w]+))?/$', views.add_member, name='add-member') inside the HTML I have this script: <script> function add_member(id){ var input=document.getElementById("myText").value console.log(id) //Correctly gets ID # console.log(input) //Correctly gets the name (string) of member instance url = "{% url 'add-member' 0 zzzz %}".replace('0', id).replace('zzzz',input); } </script> And the resulting error that I get is: Reverse for 'add-member' with arguments '(0, '')' not found. 1 pattern(s) tried: ['flexfeed/groups/add-member/(?:/(?P<pk_group>[-\\w]+))?/(?:/(?P<pk_member>[-\\w]+))?/$'] I'm having trouble understanding my error. If anyone could suggest how to fix this issue or possibly suggest a difdferent approach to this particular problem I'd really appreciate it! The end goal is that I want my page to redirect to my update view at the correct link! -

Trouble installing aldryn_forms into django project
I've used the aldryn_forms plugin before on some other projects. Typically when I install it, it's at the beginning of the project. In this case, the library is being installed after the prokect was initially deployed. I sourced my virtualenv, ran pip install aldryn-forms, added the associated libs to the settings.py file and ran migrations, but I can't escape the 500 error and stack trace that is attached below. It seems to be an issue with the state of the DB, but I'm not savvy enough with sqlite3 or Django to debug this.

User groups, and dififerent views / functions for each group
Desired Output: Employee and Client user types. If registering through the main website the user will automatically be a Client. Client type users get a different menu/dashboard/portal whatever you wanna call that. For examples. Clients can book an appointment. Then for employees that usertype is set manually in django admin. AFterwards when they log in, they get a different dashboard, say one that displays their schedule and they can put available hours. This user doesnt even need to have a registration page it can all be done in admin. From my limited understanding to bring this desired outcome to reality I must extend the userprofile? Or should I entirely create a custom userprofile using the AbstractUser abstraction? Also where does django groups come in. And is all this User model extending even necessary? Can django groups be used entirely for this project? class UserProfile(models.Model): user = models.ForeignKey(User) #define general fields class Client(models.Model): profile = models.ForeignKey(UserProfile) #freelancer specific fields class Meta: db_table = 'Client' class Employee(models.Model): profile = models.ForeignKey(UserProfile) #Employee specific fields class Meta: db_table = 'Employee' Thanks in advance!! -
Django haystack: elasticsearch how to delete by query
ElasticSearch offers a way to delete_by_query and I see that it is being called on the clear method of the backend with: self.conn.delete_by_query(index=self.index_name, doc_type='modelresult', body=query) where the query is something like this: {'query': {'query_string': {'query': "Model1 OR Model2"}}} Now, I don't know much about ElasticSearch and I created my Index like: class MyIndex(indexes.SearchIndex, indexes.Indexable): ... category = indexes.CharField(model_attr='category_id') ... And now I want to delete from my index all the documents that match category=5 and I tried something like: backend.conn.delete_by_query(index='haystack', doc_type='modelresult', body= {'query': {'match': {'category': '5'}}}) and it outputs something like this: {'_version': 4, 'created': False, '_id': '_delete_by_query', '_index': 'haystack', '_type': 'modelresult', '_shards': {'successful': 1, 'failed': 0, 'total': 2}} But it didn't delete it, I assume I need a better query, so what would it be? I also read that I can use the bulk method from ElasticSearch. Btw I also checked that I can get a "query" from a SearchQuerySet instance with: sqs.query.build_query() that gives: 'category:(5)' so it would be very helpful if I could use that query output for the delete_by_query method, but I don't know how to use it -

loading staticfiles in django template causes server error 500
I have a base.html file extended by the index.html one. In base I load some static files in the section, and other in the bottom of the file. I am trying to use the template tag for loading static files: {% load static %} However, depending where I put it, this works or fails. When the tag is on the begining of the base (first line), this always does not work. It works only when it is on the body section of the base.html and on the begining (just after extend tag) of the index.html. Where is the correct place to put it ? Should it be called only once ? -
Django Image Grid Gallery

It displays one result (image) per line (https://image.ibb.co/bVAE9b/result_2.png). The expected result should be similar to pinterest, it should be next to each other to fill up the screen.

Django ImageField save to locations
I'm able to upload photos to the media folder just fine. My problem is I can't save them to a specific folder on upload. I want the image to be saved in a unique folder based on an id being passed into the django view. Below is the code that throws the following error: views.py", line 90, in orderdetails settings.MEDIA_ROOT + '/orders/' + str(orderid) + '/' + image) TypeError: coercing to Unicode: need string or buffer, InMemoryUploadedFile found if request.method == 'POST': # Loop through our files in the files list uploaded if not os.path.exists(settings.MEDIA_ROOT + '/orders/' + str(orderid)): os.makedirs(settings.MEDIA_ROOT + '/orders/' + str(orderid)) for image in request.FILES.getlist('files[]'): # Create a new entry in our database new_image = UploadedImages(client_order=client, image=image.name) # Save the image using the model's ImageField settings filename, ext = os.path.splitext(image.name) new_image.image.save("%s-%s%s" % (filename, datetime.datetime.now(), ext), settings.MEDIA_ROOT + '/orders/' + str(orderid) + '/' + image) new_image.save() If i just use image it saves just find in the media folder.

Trying to create user types: 'Client' and 'Employee'. Would like all users who register on site to be Clients, who see different page than employee
I'm reading through these docs on Django: https://docs.djangoproject.com/en/1.11/topics/auth/customizing/#extending-user I'm just not sure which route to go. They suggest using a custom user model like so: from django.contrib.auth.models import AbstractUser class User(AbstractUser): pass Doing so, what would the procedure be to make two different user types. Should I have something like this: class Client(AbstractUser): pass class Employee(AbstractUser): pass But then how would new registered users be 'clients' when they sign up? And how would I make it so they see a different part of the site than employees? Really, i'm just looking for some guidance in how I should approach this. Any help would really be appreciated! Thanks!
