PatZilla does not serve requests when started in development mode

[amotl]

Hi there,

following up on the report #51 by @think-nice-things, we tried to reproduce the problem. We installed the software with:

virtualenv --python=python2 .venv2
source .venv2/bin/activate
pip install patzilla
pip install 'urllib3!=1.25.0,!=1.25.1,<1.26,>=1.21.1'  # Just a fix to adjust some dependency woes.

Then, we created the configuration file patzilla.ini

patzilla make-config development > patzilla.ini

and adjusted a single line, adding the depatech data source like:

[ip_navigator]
datasources = ops, depatisnet, depatech

With that, PatZilla seems to start successfully.

pserve patzilla.ini

However, when invoking a request to http://localhost:6543/navigator/, the application croaks like

same here. The browser shows:

Internal Server Error
The server encountered an unexpected internal server error
(generated by waitress)

I believe it's related to

development_mode = true

If I set it to false, the above error disappears (but yet depatech not working, see #51).

Ah, thanks for the hint! Indeed, when setting development_mode = false, PatZilla does serve requests. We will have to improve this detail within one of the next iterations.

Dear @think-nice-things,

improvements to the documentation coming from #49 will only refer to patzilla make-config production, which would be the right thing to choose when running PatZilla acquired from the package on PyPI, as it is the case here.

patzilla make-config development is only suitable when working with the development sandbox setup, where the sources of PatZilla have been acquired from the Git repository.

Through improving the corresponding documentation, I believe it will be safe to close this issue. What do you think?

With kind regards,
Andreas.

Hi again,

after scanning the issues submitted to this repository, I just discovered that @papoteur-mga already reported the same thing over at #11.

With kind regards,
Andreas.
