- # Without web-service support, an action which collects the data for displaying a list of people
- # might look something like this:
- #
- # def index
- # @people = Person.find(:all)
- # end
- #
- # Here's the same action, with web-service support baked in:
- #
- # def index
- # @people = Person.find(:all)
- #
- # respond_to do |format|
- # format.html
- # format.xml { render :xml => @people.to_xml }
- # end
- # end
- #
- # What that says is, "if the client wants HTML in response to this action, just respond as we
- # would have before, but if the client wants XML, return them the list of people in XML format."
- # (Rails determines the desired response format from the HTTP Accept header submitted by the client.)
- #
- # Supposing you have an action that adds a new person, optionally creating their company
- # (by name) if it does not already exist, without web-services, it might look like this:
- #
- # def create
- # @company = Company.find_or_create_by_name(params[:company][:name])
- # @person = @company.people.create(params[:person])
- #
- # redirect_to(person_list_url)
- # end
- #
- # Here's the same action, with web-service support baked in:
- #
- # def create
- # company = params[:person].delete(:company)
- # @company = Company.find_or_create_by_name(company[:name])
- # @person = @company.people.create(params[:person])
- #
- # respond_to do |format|
- # format.html { redirect_to(person_list_url) }
- # format.js
- # format.xml { render :xml => @person.to_xml(:include => @company) }
- # end
- # end
- #
- # If the client wants HTML, we just redirect them back to the person list. If they want Javascript
- # (format.js), then it is an RJS request and we render the RJS template associated with this action.
- # Lastly, if the client wants XML, we render the created person as XML, but with a twist: we also
- # include the person's company in the rendered XML, so you get something like this:
- #
- #
- # ...
- # ...
- #
- # ...
- # ...
- # ...
- #
- #
- #
- # Note, however, the extra bit at the top of that action:
- #
- # company = params[:person].delete(:company)
- # @company = Company.find_or_create_by_name(company[:name])
- #
- # This is because the incoming XML document (if a web-service request is in process) can only contain a
- # single root-node. So, we have to rearrange things so that the request looks like this (url-encoded):
- #
- # person[name]=...&person[company][name]=...&...
- #
- # And, like this (xml-encoded):
- #
- #
- # ...
- #
- # ...
- #
- #
- #
- # In other words, we make the request so that it operates on a single entity's person. Then, in the action,
- # we extract the company data from the request, find or create the company, and then create the new person
- # with the remaining data.
- #
- # Note that you can define your own XML parameter parser which would allow you to describe multiple entities
- # in a single request (i.e., by wrapping them all in a single root node), but if you just go with the flow
- # and accept Rails' defaults, life will be much easier.
- #
- # If you need to use a MIME type which isn't supported by default, you can register your own handlers in
- # environment.rb as follows.
