All,
I have spent the last 6hrs trying to change the default, size="30",
that is returned as a result of f.text_field... helper call. I wanted
the default width to be '16' for my application.
I am using Rails 3.0.3 and Ruby 1.8.7.
I have tried the following:
1. Adding this line in config/environment.rb:
ActionView::Helpers::InstanceTag::DEFAULT_FIELD_OPTIONS = { "size" =>
16 }
After doing this, the console yields the following:
irb(main):004:0> puts
ActionView::Helpers::InstanceTag::DEFAULT_FIELD_OPTIONS["size"]
16
=>nil
additionally, the following line in a partial...
<% ActionView::Helpers::InstanceTag::DEFAULT_FIELD_OPTIONS["size"] %>
produces a static '16' in the generated source
However...
The following html source code is rendered in my views:
<input id="party_names_attributes_0_surname"
name="party[names_attributes][0][surname]" size="30" type="text"
value="SomeText" />
2. Next I created a plugin file 'vender/plugins/default_options/lib/
default_options.rb' (also created the requisite 'init.rb'):
module ActionView
module Helpers
class InstanceTag
DEFAULT_FIELD_OPTIONS = { "size" => 16 }
end
end
end
This modification affects the value stored in
ActionView::Helpers::InstanceTag::DEFAULT_FIELD_OPTIONS["size"] but
not the results of f.text_field.
3. Finally I was able to accomplish the desired results by modifying
my plugin as follows:
module ActionView
module Helpers
class InstanceTag
DEFAULT_FIELD_OPTIONS = { "size" => 16 }
def to_input_field_tag(field_type, options = {})
options = options.stringify_keys
puts "here"
options["size"] = options["maxlength"] ||
DEFAULT_FIELD_OPTIONS["size"] unless options.key?("size")
options = DEFAULT_FIELD_OPTIONS.merge(options)
if field_type == "hidden"
options.delete("size")
end
options["type"] ||= field_type
options["value"] = options.fetch("value")
{ value_before_type_cast(object) } unless field_type == "file"
options["value"] &&= ERB::Util.html_escape(options["value"])
add_default_name_and_id(options)
tag("input", options)
end
end
end
end
Surely I am missing something. What is the 'one-line' trick to
setting the default size= option for a text_field?
Thanks
