Common View Helpers

A lightweight set of view helpers Gemini uses in all of our Rails applications.

Installation

gem install common_view_helpers

Summary

# Use words if within the last week, otherwise use date
# Show year if not this year
time_ago_in_words_or_date(date, options={})

# Output an easily styleable key-value pair
info_pair(label, value)  

# Give this helper an array, and get back a string of <li> elements. 
# The first item gets a class of first and the last, well.. last. 
# This makes it easier to apply CSS styles to lists, be they ordered or unordered.

convert_to_list_items(items)

# This works just like link_to, but with one difference..
# If the link is to the current page, a class of 'active' is added
link(name, options={}, html_options={})

# Absolute path to an image
image_url(source)

# e.g. http://localhost:3000, or https://productionserver.com
base_url

# Generate a list of column name-value pairs for an AR object
list_model_columns(obj)

# Javascript friendly (escaped) string
js_string(string)

# Generates a URL and automatically adds http:// if not already there
# Useful alongside link() when linking to user submitted addresses
urlify(address)

# Breaks up a BigNum, FixNum or Float with commas
# e.g., 532566 => 532,566 and 79593255.66 => 79,593,255.66 
commify(num)


# Converts a camelized string into snakecase (eg, SomeClass -> some_class)
snakeify(string)
