Show a nice warning message when Connect is not installed

[gioman]

Instead of:

Traceback (most recent call last): File "/home/giovanni/.qgis2/python/plugins/webappbuilder/webappbuilder_plugin.py", line 83, in run utils.resetCachedToken() File "/home/giovanni/.qgis2/python/plugins/webappbuilder/utils.py", line 208, in resetCachedToken from boundlessconnect import connect ImportError: cannot import name connect

[luipir]

a proposal. in case connect is not installed the BuildApp can be disabled. Is it feasible?

[gioman]

sounds good to me.

@gioman can you modify utils.py the funcion resetCachedToken with and see if the exception is sill intercepted?

def resetCachedToken():

global __cachedToken

__cachedToken = None

try:

    from boundlessconnect import connect

except:

    pass

else:

    connect.resetToken()

[luipir]

the message is generally gentle getting the tocken... the exception is raised on ly during toker regeneration => expiration

I think better to show a message saying htat connect is required, instead of disabling the button

Reason for this is that the user wint figuerut hat is disabled, and even if he installs connect, he will have to reload QGIS for that to take effect. If we just show a mesage telling to install Connect in case there is an exception, that provides UX

If you agree, i can add that
