When reading the source code
When you enter an existing project, you will need to check what methods each Class has.
At that time, I would like to describe below how I am confirming.
[environment] Ruby Rails Solidus
This time, I would like to explain using Rails' Solidus gem.
$rails c Enter the console with.
Therefore, as described above, the object is assigned to an arbitrary character. (Spree :: Taxon is an object)
$a.methods Execute. By executing it, the method that the object has is displayed.
$a.methods.grep /product/ Then, only the method related to product can be obtained. By using grep as described above, you can narrow down the search results and search, so I think that there are many opportunities to use it.
$a.method(:before_remove_for_products=).source_location As mentioned above, by setting method (method name) .source_location, You can also find out in which file the method is located.
