View Paths
----------
TODO...
When rendering the view for a request, the controller needs to resolve where to find each of the directories are located.
We are able to modify the order these locations are resolved by using
`prepend_view_path`
and
`append_view_path`
.
This allows us to add new paths to the beginning or end of the list used to resolve these paths.
### Prepend view path
This can be helpful for example, when we want to prepend a different directory for subdomains.
We can do this by using:
```
prepend_view_path "app/views/#{request.subdomain}"```
Then our list becomes something like:
```
[
~/rails_app/app/views/
<subdomain>
,
~/rails_app/app/views,
# ...
]
```
This will put the subdomain path at the beginning of the list.
### Append view path
Similarly, we can append paths:
```
append_view_path "app/views/direct"
```.
This will add ```
app/views/direct
``` and the end of lookup paths for views.
