Update - Please see update below.
I'm attempting to improve the performance of our ZF based CMS, and am trying out caching the Zend_Navigation object I create with the menu structure. Caching the object means I can't set the current page to active, or I'll have a copy of the menu in the cache for every page.
To allow caching of the structure, regardless of current page, I've moved highlighting of the current page in the menu to jQuery, which is working well. Then I noticed that the Breadcrumb_Helper (which uses the same Zend_Navigation object as the menu) wasn't displaying anything - obviously because I haven't got a page set to active.
Given I know the id of the page, is there a way to get inside the Zend_Navigation object to set that particular one to active?
Ideally I'd like to do something like:
$nav->findOneBy("id", $currentPageId)->setActive(true);
But there doesn't seem to be a way to access the pages in the object like this. Looking at the code, using findOneBy to get the current page, then removePage to remove it, then setting the collected one to active, and using addPage to put the collected, updated one back in might be an option, but rather convoluted.
The other option is just to cache the array I use to construct the Zend_Navigation object, which would be easier to set the current page to active, after getting the base array from the cache.
(I should point out that all the pages in the cms just have urls like /privacy, /about-us, and are routed to a default frontend module, controller and action, so there is no controllrt/action in the url to allow ZF to work out where it is.)
Update:
Ahem.... Seems like the code I suggested did actually work, and can actually be done slightly more simply using the magic finder methods...:
$nav->findOneById($currentPageId)->setActive(true);
As noted above, this does indeed work:
$nav->findOneById($currentPageId)->setActive(true);

I want to build a website, maybe similar to a movie database, where every page has, say, actors, director, year (it seems that Lektor can deal very well with such structured metadata), and I am thinking about how to realize internal links between pages on that site.
Say I have a text such as
just like in [his previous movie](link), he shows again ...
then I guess I could use the absolute path of the linked page as link target, but that makes me very inflexible with respect to changing URL structure. Can I somehow just use the ID of the target content?
Or, better yet, can I somehow automatically obtain the title of the linked page?
just like in his previous movie <<link:title>>, he shows again ...
Can I use the standard Markdown blocks for that or would I have to add some handcrafted database lookup logic?
if some contents will be changed in future. I think you can use the databag feature to implement it. you just modify the databg in case changed is need.
I'm trying to create subpanel in Account detail view where list of elements is fetched from external REST service.
I know how to define subpanel, but have no idea how to fill it with data from external network source. Was trying to use get_subpanel_data but there I can only change SQL.
Any ideas how can I do this?
When I've done this in the the past, at least with Sugar 6, I opted distinctly not to try to create a true subpanel. The data being loaded is coming from an outside source and is loaded dynamically with the page, so why present it as if it's static data coming from Sugar? Instead, I created a custom Smarty template to use as the footer on the detail page. For such an example, you can check how it works on the Calls Edit View. I think it's the footerTpl parameter in the detailviewdefs.php or editviewdefs.php. I loaded the smarty template by creating a custom detail view for my module, so custom/modules/MyModule/views/view.detail.php - extend the base Detail View class and override the display to feed Smarty new params, then your Smarty template only needs to iterate through and present the data that your view defined.
To be super-hip and abide by MVC, you could even put your custom code into your bean (if it's a custom module) or into a custom controller method, then reference that from the view.detail.php, and still feed it from there to the Smarty template.
Alternatively, you could just load JavaScript into the Smarty template and use the JavaScript to call the third-party service, parse and present it, etc.
I realize this question is a little bit old now however it comes up fairly often so why not provide an answer with a couple possible solutions. I won't get into code but more just into the design theory of how it can work. If someone needs more specific code help then that is another question.
A couple ideas...
As you mentioned you can define a custom Function which will load in Data to the SubPanel from your own SQL Query. That is one method that I just recently got to finally put to use after knowing about it for a good year and a half.
When you go this route, you are restrained to using the Columns in the SubPanel. I assume it is using the actual Metadata files to determine which Field Columns a SubPanel can use so you pretty much need your custom data in a Database table to have the same column names as the fields defined in the SubPanel Metadata.
Obviously this works great in the right situation, however not always and that leads us into the 2nd method I know of.
The other way is pretty much what #Mattew-Poer mentioned in his answer. It means abandoning the SubPanel altogether and instead generating your own HTML. This is by far my favorite and prefered way of doing it and I have been some really custom modules due to this being possible in a custom module! I will show an example below.
(Click HERE to View full size image)
In the screenshot, you can see in this example that I have something looking Similar to a SubPanel however it is not and is much for flexible and easy to customize.
Example, to the far left column in my fake subpanel is image checkboxes. When clicked on, an AJAX request is made to change the Task row Status.
After that, the checkbox image is updated to indicate the new Status state, the Modified DateTime is updated, the Status column has color background SPANS and is also updated with the correct text and background color when the left side checkbox is clicked.
Doing any of this with the standard SubPanels is a complete nightmare and would be difficult to do some of the stuff that you are open to do when you build your own version of a SubPanel.
With that said, I have built an identical clone of the above screenshot using SugarCRM default SubPanels! It was a nightmare. I could easily update the content and HTML in some of the columns. I even had the AJAX click checkbox image to update and do all the other updates I mentioned above. It wasn't too hard and worked fairly good but it had some issues.
When you do inline edit, inline create record, or subpanel paging to load different set of record. You would then lose all the custom HTML formatting that was applied. The reason is, in the SubPanel you are limited to using the After UI load logic hook. So since the "Page" is loaded already, when an AJAX request is made to add/edit the subpanel content or load a new set of items with the paging links. It only loads the SubPanel content on those events and the whole Page content does not reload. Because the logic hook only fires off 1 time after the page loads, this newly loaded subpanel data doe not receive any of your custom HTML formatting.
In my case, this means that nice looking colored background Status spans are lost, the image checkboxes are lost, and some other functionality is lost.
Now to get super technical, I could have gone another 3rd route and instead made new Custom Field Types for each SubPanel filed that I needed to apply custom HTML to. This process is super hard in my experience and in some cases it really isn't the BEST solution.
Because of the reason explained, this is why my new modules use the Custom HTML route to generate my own version of a custom subpanel or whatever Data is needed in my Module pages! So far it is working better than I imagined and has opened doors for me to build custom SugarCRM modules that I previously didn't even realize would be possible to build due to some of the issues I mentioned above. Now I bypass them altogether and open the door to do pretty much anything!
I've got some really cool stuff for SugarCRM in the works right now. If anyone has any questions feel free to ask in a new question or for me personally in a comment here.
I am creating an application and trying to figure out best way to deal with navigation in it. User can choose different view settings (which content to show and options to filter it). Part of settings is stored in backend in user preferences model. Another part is stored in url and managed by router. But there is more settings I want to keep. The reason: I want to be able to refresh content therefore I need to keep settings somewhere, not update content on user actions and forget how I came to this state. My question is: what is the best place for such settings? Collection object? View object? My own controller?
P.S. to make it more clear, I'm working on rss reader application. And I want, for example, to show last week posts from certain feeds which are starred etc.
Save it in the URL. Thats the only place you can really rely on. If you need more then routes use query parameter like in a classic web application and use them in the view.
I have this gwt app which say, runs on http://mygwtapp.com/ (which is actually: http://mygwtapp.com/index.html)
The app host a database of users, queried by searching usernames using the search view and results are shown in the user results view. Pretty useful enough. However I need to bb add a way that user view can be viewed by just typing http://myapp.com/user123
I am thinking that the question I have here, the answer is a server side solution. However if there's a client side solution, please let me know.
One fellow here in StackOVerflow suggested that the format would be like this:
mygwtapp.com/index.html#user123
However the format is important to be like: http://myapp.com/user123
The 'something' in 'http://host/path#something' is a Fragment identifier. FIs have a specific feature: the page isn't reloaded if only FI part in URL changes, but they still take part in browser history.
FI's are a browser mechanism that GWT uses to create "pages", i.e. parts of GWT application that are bookmarkable and have history support.
You can try to use an URL without # (the FI separator), but then you will have a normal URL, that reloads the page with every change and it could not be (easily) a part of a normal GWT app.
mygwtapp.com/index.html#user123
That would be using the History mechanism (http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html) which I would add is the recommended way of doing it.
However, if you insist on using something like http://myapp.com/user123, one of the possible ways is to have a servlet which accepts this request (you might have to switch to something like http://myapp.com/details?id=user123). The servlet will look up the DB and return your host html back. Before returning it will inject the required details as a Dictionary entry in the page (http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/i18n/client/Dictionary.html) On the client you can read this data and display on the UI
How would you implement caching of the layout content in Zend Framework?
In the layout.phtml I do: $this->layout->content and I want the content of this variable to be cached. The other widgets from the layout are real time (or cached other way).
The best bets are:
static cache (the fastest)
page cache
My pages already have unique page id (canonical), so it could be used as page cache tag.
Potentially looks like I have to overload __get property of the layout.
I'm trying to do something like the layout of SO (user panel at the top, rest cached for all).
I assume, site should work without JavaScript.
You might want to have a look at the Front Controller Cache plugin weierophinney describes. The problem probably is that you don't want the script to stop on cache hit. So you don't exit; the the script, you could work with $request->setDispatched(true) within the plugin. (You'd need a new request-object for every different cacheable).
Another approach could be that you don't use the dispatchLoopStartup but the preDispatch in your plugin and reset the dispatching there.
They way to go actually depends on how you load all the other stuff (be it cached or not). (E.g. the ActionStack pushes a new request to the dispatcher).
