Grab host app active record objects when engine and host app have same model names

ruby-on-rails,ruby,database,performance,model

Use ::Article to refer to the top-level namespace class, and MyEngine::Article to refer to the engine's class.

Keep leading zeroes when converting string to integer

ruby-on-rails,ruby,rack,multipart

Short answer: no, you cant. 2.1.5 :001 > 0001 => 1 0001 doesn't make sense at all as Integer. In the Integer world, 0001 is exactly as 1. Moreover, the number of leading integer is generally irrelevant, unless you need to pad some integer for displaying, but in this case...

Recursive solution doesn't iterate correctly

What you are doing will access the fourth character of String s.

The index starts from 0. That means s.split[3] will...

Make instance variable accessible through hash in Ruby

It's not "through Hash", it's "array access" operator. To implement it, you need to define methods: def [](*keys) # Define here end def []=(*keys, value) # Define here end Of course, if you won't be using multiple keys to access an element, you're fine with using just key instead of...

When to use (:method) or (&:method)

When you say :method, you're using some nice syntactical sugar in ruby that creates a new Symbol object. When you throw an ampersand before it (&:method), you're using another piece of sugar.

.split and regular expression in Ruby

Very well. Taking inspiration from this answer, the regular expression you are looking for is: values.split(/,(?=(?:[^']*'[^']*')*[^']*$)/) This will not work if you have escaped quotes, for example (e.g. "'O\'Reilly\'s car'"). However, this looks a bit like an XY problem. If you want to parse CSV, as it seems, and if...

Does rails have an opposite of `parameterize` for strings?

Allowing some enabled and disabled option on collection_select

collection_select internally relies on options_from_collection_for_select helper. Rather than using the collection_select directly, you can use select and pass the result of a options_from_collection_for_select call. The reason you may want to call options_from_collection_for_select directly, is because this method also accepts an optional selected parameter that could be used to pass a...
