Web Page Comes Up But Render Not Displayed about cqparts-server HOT 17 CLOSED

I forgot to check the JavaScript console. Let me do that before you spend any time on this issue.

from cqparts-server.

It actually watches a directory for any changes to .py files, so ./server -d working_directory , also if you run a script with display(object) in it the server will display it.

Still very much pre-alpha , but keep the issues coming if you are using it.

from cqparts-server.

Ah, ok. I didn't realize it had to be run against a directory.

Still very much pre-alpha

Understood. Thanks for putting this out there. Multiple CadQuery community members have hacked together their own variations enabling this type of workflow. I was curious how it works.

but keep the issues coming if you are using it.

This is the first time I've ever touched Go, so filing issues is probably all I'm good for. Probably won't be able to do any code contributions.

There are sections of the viewer in cadquery-gui that you might want to take a look at to see if they can be reused.

from cqparts-server.

thanks @jmwright will investigate and pilfer code as needed. :)

My intent is to have a development helper and a catalogue explorer to start and going into the future a cache proxy for cqparts (and friends).

from cqparts-server.

@jmwright also check out https://github.com/zignig/cqparts-bucket for some of the messing about I have done with cqparts ( and the awesome of CadQuery ) , looking forward to the pythonOCC transmogrification. Willing to assist on that, we should get @tpaviot on board for the transition.

Hmm, still not working for me. I have my environment(s) set up in weird ways because of the FreeCAD module development, so that's probably the issue. However, due to #2 I can't seem to figure out what the errors are.

Cool. I noticed your pizero script. I'm assuming that's a Raspberry Pi Zero?

from cqparts-server.

It is a Rasberry Pi Zero and a basic arduino , I'm making a case that will alter itself based on the board.

from cqparts-server.

There's an issue when the FreeCAD module is installed and this server is used. When FreeCAD starts up it runs Init.py for each of the workbenches it finds. The CadQuery module manipulates sys.path to load its libs, and so when a file is saved and cqparts-server loads FreeCAD, the server starts looking at the module's embedded version of cqparts. The module doesn't include the web rendering templates or anything else related to the web view because it doesn't need it. I can add those components in, but then the user may not be aware of which version of cqparts they're running. I may just have to move the sys.path manipulation into InitGui.py, which isn't called until someone actually selects the CadQuery workbench.

Anyway, I still get this error after doing pip install cqparts in the terminal, even after I uninstall the CadQuery module.

If I fire up a Python console and try that import in the virtual environment, it works fine. The FreeCAD module can also use display just fine.

from cqparts-server.

If I strip the /usr/bin from this line I get further, but I still get an error.

I don't see a separate package for the web display in cqparts. What am I missing?

from cqparts-server.

I've copied the web-template directory into the virtual environment, and I've filed an issue on cqparts proper about the missing directory.

I still have to modify the python2.7 line in build.go, and I still don't have anything displayed when I save the file. I see the grid in the browser, and there are no errors in the terminal. However, I do see the following in the console on Firefox in Ubuntu 17.10.

from cqparts-server.

Ok, the server looks for the Case file so it can display on start up. I think that you will need the new release from @fragmuffin of cqparts for this to work correctly. The new display() works with cqserver.

The web pages are baked into the cqparts-server binary so there should be no need to copy them.

Once the new release of cqparts is out , this should actually work.... ;)

from cqparts-server.

The rendering does work with the new release of cqparts. However, I'm not sure what to do about having to change the python line in build.go.

from cqparts-server.

Can you post the change you had to make and I will investigate.

from cqparts-server.

I changed this line to this:

cmd := exec.Command("python2.7", file)

I'm not really sure why that would fix it. If I do which python2.7, it shows /usr/bin/python2.7

from cqparts-server.

very weird. But it's working otherwise ?

from cqparts-server.

Yeah, it's rendering now. I think this issue can be closed since the original problem has been solved.

from cqparts-server.

Thanks for the help.
