ruby on rails - Create a wizard that works with multiple Resources -

-

I'm writing an app that has the "Wizard" type input section, think of MS Windows Installer.

I find it difficult to find out how fast the best way to do this with rail. I can do it in a non-pure way (already done for version 1), But I am trying to be a bit idiotic at this time.

Here's the situation I have a 5 step wizard that has to collect information. Deal with steps 1, 2, and 4 resources. Phase 3 deals with multiples of Resource B and they have to be associated with Resource A. Step 5 is only a confirmation.

So I have my resource controller and my resource B_controller ... but they save / update only one resource I'm guessing that I have a wizard for each step in the process- the controller Should be installed, but I'm not sure how routing should work.

For example ... 

  Wizard Controller & lt; ApplicationController def stepOne @resourceA = ResourceA.new end def stepTwo @resourceA = params [: id] end ... def stepFive end end

and then see my view at StepOne: 

  & lt; Form action = '/ resource a / new' / & gt;

and on StepTwo verb 

  & lt; Form action = '/ resourceA / 12345 / edit' / & gt;

etc.

But then my resource A and Resource B controllers should know how to redirect the appropriate steps in the Wizard / Controller. Tangled dirt!

Am I anywhere near the right path? Or is there a plug-in mechanism or plugin for such things.

It is important to provide a minimum set of tasks for a RESTful service, using a client Understand the difference between (It provides the right data knows).

  • For example, you should be able to post / resourceA / 12345 to edit that existing resource
< / Li>

  • A guaranteed service does not guarantee any guarantee about other URLs will return meaningful response.

    • A notable example is that REST will not specify that / resource A / 12345 / edit is designed to edit that resource An HTML form will return This is a feature of the HTML application, which provides a method to display the positions described above.

    • To expand this principle, it is perfectly acceptable that there are many editing modes which define all the POST URLs as defined by the edit Action Generally, whatever is used with the .attributes = ... , you can see the attributes that are crossed, which is the information that HTML buttons use with the form submission To do this, to decide which page to use the user's Should look forward.

    • It can rely on a control method to deal with submissions of multiple pages, but with clever verification and select overwriting accessories, how do you use the users' app? Can keep a lot of control over it.

    • You should also be able to understand that this method is not restricted to users only in the order presented in the form to restrict the attributes of a tired customer a resource The principle post may be updated for the all attributes associated with, instead of one page presented by your wizard. Believing the methods of your model, it is necessary that everything can be done just to work.

    I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

    url rewriting - How to implement the returnurl like SO in PHP? -

    -
    This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

    Which Python client library should I use for CouchdB? -

    -
    I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
