Unable to load blueprint

[davidmurray]

Hi,

When I try to load the blueprint in the following way:

from rqmonitor.bp import monitor_blueprint
app.register_blueprint(monitor_blueprint, url_prefix="/dashboard")
from .backend import config
app.config["RQ_MONITOR_REDIS_URL"] = config.REDIS_URL # This looks like :  f"redis://:{REDIS_PASSWORD}@{REDIS_IP}:{REDIS_PORT}/0"

app.config["RQ_MONITOR_REFRESH_INTERVAL"] = 10

I get the following HTTP reponse when I try to load the page:

{"message":"RQ Monitor Global Exception","traceback":"  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/flask/app.py\", line 1950, in full_dispatch_request\n    rv = self.dispatch_request()\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/flask/app.py\", line 1936, in dispatch_request\n    return self.view_functions[rule.endpoint](**req.view_args)\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/rqmonitor/decorators.py\", line 32, in _wrapper\n    raise RQMonitorException(**kwargs).with_traceback(tb)\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/rqmonitor/decorators.py\", line 22, in _wrapper\n    inner_response = func(*args, **kwargs)\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/rqmonitor/decorators.py\", line 11, in _wrapper\n    _rendered_template = func(*args, **kwargs)\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/rqmonitor/bp.py\", line 99, in home\n    site_map[rule.endpoint] = url_for(rule.endpoint)\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/flask/helpers.py\", line 370, in url_for\n    return appctx.app.handle_url_build_error(error, endpoint, values)\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/flask/app.py\", line 2216, in handle_url_build_error\n    reraise(exc_type, exc_value, tb)\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/flask/_compat.py\", line 39, in reraise\n    raise value\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/flask/helpers.py\", line 358, in url_for\n    endpoint, values, method=method, force_external=external\n  File \"/home/poga/anaconda3/envs/analyses_images/lib/python3.7/site-packages/werkzeug/routing.py\", line 2179, in build\n    raise BuildError(endpoint, values, method, self)\n"}

Why is that?

Thanks! David

Hi David,

There are some issues occuring while importing the monitor_blueprint (my bad, didn't check for it previously). Although above seems not be directly related to static file issue https://github.com/pranavgupta1234/rqmonitor/issues/7 but I was able to reproduce some kind of url Build error as above while configuring for static_url_path for blueprint. I am looking more into it.

Hi David,

v1.0.0 should have fixed this. I checked with above example and it works fine now. Let me know if same error pops up again. Also as refresh interval is in ms and I think you want 10 seconds for RQ_MONITOR_REFRESH_INTERVAL so you should use 10000 for the same.

Hi,

Thanks for the info. I'll have a go at this new version next week and I'll update this issue. Also, thanks for the tip about the refresh interval !

Regards. David

@pranavgupta1234 Unfortunately, I am still getting the same error with rqmonitor 1.0.0:

Same error for me too.

Hi @davidmurray @sti2dSinBastia

The issue was due to accessing app level rules for generating site_map. I have added check to filter only rqmonitor specific endpoints to be included in site_map in https://github.com/pranavgupta1234/rqmonitor/commit/eac9f6a51b179118d06c1dbe5bd41800f6fca862

Give it a go by directly installing from master, it should have fixed this issue.

[sti2dSinBastia]

It works ! Thank you, Very good job !
