The weird thing is that when I've tried the docker option it works fine.
Could you help me with this?
Why do I have to GET twice each time I refresh the page?

I am looking on the datatables website, but not sure how to integrate into the flask-gentelella
Installed the pip packages in my environment and set the flask app, but can't seem to run flask-gentelella?

if i want to import pages from grafana , any suggestion?
If I set the db as a file in the disk, the template works fine, but setting up as a db in Pythonanywhere, I often get the error "in cursor: raise errors.OperationalError("MySQL Connection not available.")".
Reloading the page once or twice works, but after a few minutes being idle, when I try to click to something, then it happens again. Over and over.
PS: the older website I had in Pythonanywhere used the same mySql configs and was working fine.
I just can't figure out what's happening. Do you know about this issue?
hi,
your work is awesome! there are very few readymade flask admin templates out there. FYI, if you put this on themefores - there will be a lot of us who are willing to pay for it.
thanks!
I cant test this admin templete in the given demo, is the site down or something ?
I am struggling a bit to follow the process that the signup form uses.
I can see the route.py which pulls in the forms.py and makes an instance of the form
login_form = LoginForm(request.form)
I can see the create user form has the
onclick="signup()"
which it gets from static/build/js/login.js and that this posts the data to /create_user as json and if successful it simlautes a click on the login form.
what i dont get is where is the login submit going? I assume it posts to itself but i dont see how that is happening.
Could you summarise for me pls.
Sorry if these are noob questions im only a beginner.
Oh and is there a reason that the login page includes the js scripts inline in the body instead of in a scripts block?
Hi
My OS is Windows 10.
I was able to run it successful in cmd by following those instruction. I am wondering how to run it in Pycharm?
Thank you.
I'd like to run this code. However, after pip install -r requirements.txt and try to run on my mac laptop. I got some error message like below:
@app.before_first_request AttributeError: 'Flask' object has no attribute 'before_first_request'. Did you mean: '_got_first_request'?
Due to package version. Would you help add the version number in the requirement.txt which could run the code? Thank you.
when ever i execute on my windows 10 i get
Error: Detected factory "create_app" in module "app", but could not call it without arguments. Use "FLASK_APP='app:create_app(args)'" to specify arguments.

Can someone give me pointers to getting the tests to run in a docker container?
Here is the Dockerfile I am using:
FROM python:3.6
COPY requirements.txt .
COPY requirements_dev.txt .
COPY ./ /app
RUN pip install -r requirements_dev.txt

And the docker-compose.yml file I am using:

Here is the command I am using to run the tests:
docker-compose run web coverage run --source=../app -m pytest ../tests/
And this is the error I am getting:

Since I am running inside a Docker container I am confused as to how it is even detecting /Users/jack/code/flask-gentelella/tests/conftest.py
(which is on my host machine).
I found references online saying I need to make sure to delete any __pycache__
folders before building the docker image, but that did not help. I also made sure there was no volume sharing between the container and my host machine.
Any help would be appreciated.
