I have been looking around but haven't found what I needed. Basically, I have a few small modules which have just the DefaultController and a few bigger ones with multiple controllers. My rules for the small modules work fine but the ones of the big modules won't. Here are my rules:
'<module:\w+>/<action:\w+>' => '<module>/default/<action>',
'<module:\w+>/<action:\w+>/<id:\d+>' => '<module>/default/<action>',
'<module:\w+>/<controller:\w+>' => '<module>/<controller>/index',
'<module:\w+>/<controller:\w+>/<action:\w+>' => '<module>/<controller>/<action>'
The first two rules work fine, allowing me to access:
http://host/news/create and routes to news/default/create.
The last two are supposed to do the following:
http://host/posts/category which should route to posts/category/index
and
http://host/posts/category/create which should route to posts/category/create
They do not seem to work, sadly. Any suggestions?
It looks like the first rule will capture any request that could also match the third one.
Think of it in the terms of its representing regex: w+/w+: as a generic rule for routes in Yii, more prescriptive rules should go on top and less more generic, catch-all rules should be at the bottom.
Now the best way to obtain what you need would be to do something along the lines of:
'<module:news>/<action:\w+>' => '<module>/default/<action>',
'<module:news>/<action:\w+>/<id:\d+>' => '<module>/default/<action>',
'<module:posts>/<controller:\w+>' => '<module>/<controller>/index',
'<module:posts>/<controller:\w+>/<action:\w+>' => '<module>/<controller>/<action>'
this way you are explicitly expressing the routes for each of the modules in a clear and immediate way which will also help you in the long-term.
