Custom URL rules with modules in Yii2

Question

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.

Wouldn't this eventually end up with a huge list of rules? Or is there a way to add multiple modules to a single rule?

Ideally yes, but it really depends on a case by case basis. In this situation the first two "default" ones might be the specific rule for any module, but that you need to ensure all the modules have a generic structure and would respond to that query correctly. Secondly this is an architecture problem rather than anything else: by making two rules that respond to w+/w+ you're creating a conflict of routes, where the first take precedence, hence the need to differentiate. You can aggregate multiple modules in the same rule in the following way: <module:(posts|otherModule)>/<controller:\w+>.
