using Liquid variables inside of a liquid tag call

Question

I made a custom link tag in Liquid and I am trying to be able to pass liquid variables into the call for that tag like so

{{ assign id = \'something\' }} //          


        

Answer 1

This solved the case for me context[@markup.strip].

My problem was that i wanted to be able to pass a variable to my custom Liquid tag like this: {% get_menu main_menu navigation.html settings.theme.id %}

In order to do this i first split the variable string into different varaibles on every space character.

class GetMenu < Liquid::Tag
    include ApplicationHelper
    def initialize(tag_name, variables, tokens)

        @variables = variables.split(" ")

        @menu_object = @variables[0]
        @file_name = @variables[1]
        @theme_id = @variables[2]

        super
    end

    def render(context)

        # This is where i use context[@theme_id.strip] to get the variable of "settings.theme.id"
        content = CodeFile.find_by(hierarchy: 'snippet', name: @file_name.to_s, theme_id: context[@theme_id.strip])

        @menu ||= Menu.find_by_slug(@menu_object)

        context.merge('menu' => @menu)

        Liquid::Template.parse(content.code).render(context)

    end

end

Liquid::Template.register_tag('get_menu', GetMenu)
