Custom view helper

Rails
1

How would I take the following and make it a view helper?

site.name
site.address
site.city, site.state.upcase,
site.zipcode

Try following code

return “#{site.name}
#{site.address}

@{site.city},#{site.state.upcase}, #{site.zipcode}”

Thanks, I am looking to put in in the helper module as a view helper.

Hi Chris,

You can use the above code by putting it in a helper function like

def function_name(site)
return “#{site.name}
#{site.address}

@{site.city},#{site.state.upcase}, #{site.zipcode}”

end

You need to include the helper and call function from view page, like

<%= function_name(site) %>

Thanks. How would I insert erb into this. <%= link_to site.name,
site_path(site) %>. I cannot seem to get it to interpret the erb it
comes out like a string.

I like to use %Q{}'s so I don’t have to sweat quotes… see the last
line for how to use link_to (or any other view helper for that matter)

def function_name(site)
%Q{#{site.name}

#{site.address}

#{site.city}, #{site.state.upcase}, #{site.zipcode}

#{link_to site.name site_path(site)}
}
end

I am getting:

undefined method `link_to’ for #SitesController:0x6ccf090

This works for me in 2.3.5

ActionController::Base.helpers.link_to(…)
