    Twitter Bootstrap Modal Won’t Load Content from Another (“Remote”) Page 

    Short answer

    You apparently need a skeleton [modal … modal-body … /modal] for your data-target, not just an empty modal with the data-target.

    A Programmer’s False Assumptions – The API is Broken or Old

    Initially, I was concerned that my Rails plugin wasn’t using a version of Bootstrap that didn’t include the remote loading of a page into the modal (via href attribute). That functionality has only existed since 2.0.4.

    However, when I checked the script being loaded into the project against the current bootstrap-modal.js on github, the MODAL DATA-API section was the same. Repeated checks of the javascript being loaded into my project confirmed that the code was up-to-date enough.

    Maybe a Little Too Helpful

    The forums discussing how to load remote content into a Bootstrap Modal suggested that the data-target div could be empty:
    Original calling page sample:
    The contents of the calling page div never changed.

    Settings...
    .
    .
    .
    
    

    “Remote” page sample

    ...extra code here...
    
    ...extra code here...
    

    What Was Really Happening

    The documentation states that, “If a remote url is provided, content will be loaded via jQuery’s load method and injected into the .modal-body.”

    From there, I put a stub modal-body in my calling page’s modal and discovered that modal-header, modal-body, and modal-footer appeared to be getting replaced now!
    New calling page:

        I’m using Bootstrap 2.1.x in this case–it appears older versions may not work.

        Also, the outer modal class should be removed–otherwise the number of backdrops will double every time the modal is shown.

        Just noticed my response is missing. Not sure why, but trying it now with an updated version of Disqus.

    Experimenting with Rails’ String Manipulation from ActiveSupport::CoreExtensions::String::Inflections 

    This is my experimentation with the string manipulation methods used [largely internally] in Rails. This is largely a repeat of the documentation here, but I did dig into pluralize/singularize and a couple of other examples more in depth. Look at [path to active_support gem version]/lib/active_support/inflections.rb for the full list of plural, singular, irregular, and uncountable regular expressions and words.

    require 'active_support/core_ext/string/inflections'
    # camelcase, camelize 
    "separate_words".camelize # SeparateWords
    "active_record".camelcase(:lower) # separateWords
    
    # classify - converts to first upper CamelCase, last word made singular
    "this_and_thats".classify # ThisAndThat
    
    # constantize - looks for declared constant with the name specified
    "Integer".constantize # returns constant [class] Integer
    "integer".constantize # results in NameError: wrong constant name integer
    "Boo".constantize # results in NameError: uninitialized constnat Boo (assuming it isn't declared)
    
    # dasherize - underscores to dashes
    "a_b_c".dasherize # a-b-c
    
    # demodulize - removes module namespace from module in string.
    ModuleA::SubModule::Module".demodulize # Module
    
    # foreign_key - create name of a foreign key to class name, optional parameter to separate class from id
    "Integer".foreign_key # integer_id
    "Integer".foreign_key(false) # integerid
    
    # humanize - capitalizes first word, down cases rest, turns underscores into space.
    "McLean".humanize # Mclean
    "Apple_Banana".humanize # Apple banana
    
    # parameterize - replaces special characters in a string, default separator is '-'
    #   - whitespace is a special character here, underscore is not
    #   - consecutive special characters become a single separator
    #   - converts to lowercase
    "[email protected]!Banana".parameterize # "apple banana"
    
    # pluralize 
    "raman".pluralize # "ramen" -- apparently, "man" --> "men" even on a made-up word
    "jazz".pluralize # "jazzs" 
    "box".pluralize # "boxes"
    "beep".pluralize # "beeps"
    "moose".pluralize # "mooses"
    "rhombus".pluralize # "rhombuses"
    "octopus".pluralize # "octopi"
    
    # singularize
    "ramen".singularize # "raman"
    "jazzes".singularize # "jazze"
    "boxen".singularize # "boxen" -- yeah, not a real word again
    
    # tableize - snake_case string and pluralize last word
    "RedHeadedStepchild".tableize # "red_headed_stepchildren"
    
    # titlecase / titleize - capitalize all words, 
    "two_three-four.five:six".titleize # "Two Three Four.Five:Six"
    
    # underscore - snake_case words (opposite of CamelCase) and covert :: to /
    "Number::OneTwo::Integer".underscore # "number/one_two/integer"
