# Tiny Tip: Debug current request in views
* Trying to understand how a legacy app is set up?
* Don't know what you are looking at?
Try inspecting all the requests by adding `params.to_yaml` or `params.inspect` or `debug(params)` or `params.to_unsafe_h` to your layout file:
#app/views/layouts/application.html.erb
```
<%= params.to_yaml %>
<%= params.inspect %>
<%= debug(params) %>
<%= params.to_unsafe_h %>
<%= yield %>
```
For example, `<%= params.inspect %>` will give you
```
#"inboxes", "action"=>"edit", "id"=>"4"} permitted: false>
```
`<%= params.to_unsafe_h %>` will give you
```ruby
{"controller"=>"inboxes", "action"=>"edit", "id"=>"4"}
```
`<%= debug(params) %>` will give you (BEST)
```
#"inboxes", "action"=>"edit", "id"=>"4"} permitted: false>
```
