I was wondering, In a RemoteAction function in an apex class can or should this be able to access the current force.com site page? I would like to access and write to cookie parameters from within my static remote method but I'm guessing this may not be possible?
If not, any suggestions on how to get around this would be useful.
Thanks in advance.
Remote Action method runs in an.asynchronous mode.Hence accessing values from url parameter will get you null values.If you need any static values for your apex class to process use the parameters.pass from page to your apex method using parameter .
There is one way that i recently discovered to do this
Pass them in from the script on the page using {!$currentpage.parameters.something}
You still need to check for nulls in the code because it might legitimately be null

In Rails 4 application I need to reload routes (routes.rb) for every request before the application uses it. Where should I put MyApplication::Application.reload_routes!
I have tried to put it in config/applicaion.rb,config/environments.rb but it's not working.
I have also tried to put it in before_filter of ApplicationController and it's also failing.
RoR api is brief on how to use it.
So any assistance/guidance on this will be greatly appreciated
Seriuosly i would never do that. It is massive intervention into Rails internals. Just configure one dynamic route to a single controller. Then load some Command(Service)
according to the dynamic part of the url from the db, deserialize, instantiate and pass
the current controller as a reference to this dynamic service constructor.
The dynamic service you are loading should be implemented according to the following refactoring technique:
Replace Method with Method Object
Another Option would be to load a lambda/Proc because it would automatically have the controller scope once instantiated
I'm just starting out with ColdFusion OOP and I am wanting to make a DIV which shows different links to users depending on what page they are on and what login rights (role) they have. Basically a 'context' menu.
Should I put this toolbar/navigation DIV in a .cfm or .cfc file?
To reiterate; The cfm or cfc file needs to know what page the user is on and will also check what role they have. Depending on these two pieces of information it will display a set of links to the user. The role information comes from the database and stored in a SESSION variable, and to find out what page they are on I guess it could use #GetFileFromPath(GetBaseTemplatePath())#.
My first thought was to have a normal .cfm file, put all the presentation and logic in that file (the HTML and lots of <cfif> statements) to ensure the correct information is displayed in the DIV, and then use <cfinclude> to display it on the page. Then I started thinking maybe I should make a Custom Tag and ask the calling page to pass in the user's credentials and the #GetFileFromPath(GetBaseTemplatePath())# as arguments and then have that Custom Tag return all the presentational data.
Finally I guess a CFC could do the above as well, but I'd be breaking the 'rule' of having presentational and logic data in a CFC.
Any suggestions on the best practice to achieve what I'm trying to do? It will eventually serve thousands of customers so I need to make sure my solution is easy to scale.
Anything that outputs HTML to the screen should be in a .cfm file.
That being said, depending on your need, you could have methods in a CFC that generate HTML, but the method simply returns the HTML as a string.
In programming, there are very few absolutes, but here is one: You should NEVER directly output anything inside of a function or method by using output="true". Instead, whatever content is generated, it should be returned from the method.
If you will have a need to use this display element more than once, a custom tag might be the best way to go rather than an include.
I see security as being a combination of what menu items I can see and what pages can be ran.
The main security function is inside of the main session object
On the menus
I call a function called
if (session.objState.checkSecurity(Section, Item) == 1)
then ...
For page security
function setupRequest() {
...
if (session.objState.checkSecurity(getSection(), getItem()) == 0) {
location("#request.self#?message=LoginExpired", "no");
return;
}
...
}
The particulars of what checkSecurity can do varies from application to application, but it is tied into how FW/1 works. The following security variations exist:
session.objState.checkSecurity(getSection())
session.objState.checkSecurity(getSection(), getItem())
session.objState.checkSecurity(getSection(), getItem(), Identifier)
None of the presentation files know anything about security.
Rules by which I live:) :
No CF business logic in CFM files. Just use some service which will serve template and provide needed data.
navService = com.foobar.services.Navigation(form, url);
and later output #navService.GetNavConent()#
No direct output from CFC files, functions should always return content. For example, make one function which makes one link based on some logic, second which wraps that and returns to cfm template.
Also one more hint, avoid using application and session scopes in your services.
This makes refactoring, testing and debugging too difficult.
For session you can make session.currentUser , CurrentUser.cfc which provides all things you need. e.g. session.currentUser.isAuthorized("backend/administration") and if true, show link to backend/administration.
Same for application, if you need locale, applicaiton wide setting or some singleton, make application.applicationSettings, ApplicationSettings.cfc and use that to retrieve all info you need in cfc's.
These rules will make your application to be easier to test and debug, and really easy to migrate tomorrow on some javascript based UI like Angular or backbone.js since all th edata you need is already in CFC and theoretically you just need to put remote in CFC or make some remote facade in the middle and you're done.
I'm working with SWFUpload and Django, and I've noticed that authentication tends to break.
There is one part that is holding me up and I'm looking for direction more then a solution as I think know the solution is not yet available. (So I'm making it. )
I need to know how Django creates the WSGI request-object and how it's handled.
After looking at the source of django, it seems that csrf is done via the WSGIobject which have the appropriate cookeis appended to it. Naturally flash posts do not support this unless specified. SWFUpload offers the ability to send cookie data in the post params via a plugin, however I'd like to send them via headers on the URLRequest object. ( So that the Auth-Middleware and CSRF-Middleware can see it. )
My goal is to upgrade SWFUpload to send headers containing the values for what ever objects I pass it. The hard part for me is to figure out how those headers will be interpreted.
How does Django create the request.META object? | Where is the request.session object created?
I'm reading up on the WSGInterface now, but I'd like to accelerate this research. Thanks!
I believe what you're looking for is django.core.handlers.wsgi.
In drupal 6 I'm trying to execute a function on every page and output a different link based on what IP address someone is coming from. However, when I try this, it seems that the result is getting cached. I have tried this as a module and in template.php, but have not gotten results. What is the best approach to make sure this function executes on every page load? Or is there an easy way to create a template variable that does not get cached?
Is it possible for you to use a block instead with BLOCK_NO_CACHE or BLOCK_CACHE_PER_USER as the block caching policy? If you put a block like this in a region above/below you could achieve a very similar effect on any page you like, node or otherwise.
Im currently using ie as an active x com thing on wxWidgets and was wanting to know if there is any easy way to change the user agent that will always work.
Atm im changing the header but this only works when i manually load the link (i.e. call setUrl)
The only way that will "always work," so far as I've been able to find, is changing the user-agent string in the registry. That will, of course, affect every web browser instance running on that machine.
You might also try a Google search on DISPID_AMBIENT_USERAGENT. From this Microsoft page:
MSHTML will also ask for a new user
agent via DISPID_AMBIENT_USERAGENT
when navigating to clicked hyperlinks.
This ambient property can be
overridden, but it is not used when
programmatically calling the Navigate
method; it will also not cause the
userAgent property of the DOM's
navigator object or clientInformation
behavior to be altered - this property
will always reflect Internet
Explorer's own UserAgent string.
I'm not familiar with the MSHTML component, so I'm not certain that's helpful.
I hope that at least gives you a place to start. :-)
I did a bit of googling today with the hint you provided head geek and i worked out how to do it.
wxWidgets uses an activex rapper class called FrameSite that handles the invoke requests. What i did was make a new class that inherits from this, handles the DISPID_AMBIENT_USERAGENT event and passes all others on. Thus now i can return a different user agent.
Thanks for the help.
Head Geek already told you where in the registy IE will look by default.
This is just a default, though. If you implement [IDocHostUIHandler::GetOptionKeyPath](http://msdn.microsoft.com/en-us/library/aa753258(VS.85%29.aspx) or [IDocHostUIHandler2::GetOverrideKeyPath](http://msdn.microsoft.com/en-us/library/aa753274(VS.85%29.aspx), IE will use that registry entry instead.
You'll probably want to use SysInternal's RegMon to debug this.
