Does CouchDB allow you to call an external web service from within the definition of your view? I basically want to resolve a woeid (where on earth id) using Yahoo's API's and update a view accordingly.
No, you cannot. The reason is that view indexes need to be completely self-contained. Using any external source would require the view index to be recalculated upon every change of that external resource. (not even to mention that CouchDB has no way of knowing when an external change has occurred.)
For this same reason, you cannot use CommonJS modules in your map/reduce (view) functions, as the server would have no way of knowing what changes to any CommonJS modules (in any design document) would have any effect on a given view. The only solution would be to update the view every time a change is made to any design document, which nobody would ever want.
I would recommend you look into GeoCouch for utilizing positioning in your project.

In Kentico 11, in a custom module you are developing, when using a custom Page Template (portal mode) for the UI Element, where is the appropriate place to host Transformations used by web parts of that template? "Appropriate" meaning the transformations can be bundled with the module for import/export operations or at least grouped with it logically in Kentico admin?
The Kentico Custom Module app doesn't contain a Transformations tab for its Classes.
Repeater web parts used on the UI page template only list Custom Tables and Page Types when looking for transformations. Transformation doesn't seem to be supported for a Custom Class.
I could create a standalone container Page Type to host all transformations for the module, however this would be outside the module. These transformations would use data from Classes in the module (through repeater web parts and query data sources for example). It seems odd to put them outside so I am suspicious of doing this.
Up until now I've only used the out-of-box tab and listing web parts to create custom modules. Now I need to get into more customization, and prefer the portal mode to easily build templates using web parts. Transformations seem to be the missing consideration in this development flow.
Neither can I find Transformations mentioned in the Custom Module documentation. Kentico Documentation I'm referencing is:
Creating custom modules
Manually creating the interface for custom modules
Martin Hejtmanek's Module development articles like this one
I can find a place to put my transformations. I'm looking for thoughts about where to best put them and bundle them with my custom module work.
Your findings are a shortcoming in the module documentation. The documentation talks in great detail on how to build the module and display it within the Kentico UI but talks little to none on how to display that content outside of Kentico on the public facing website.
What you mentioned, using a custom Page Type as a container is a simple easy approach and I believe you can bundle this with your module. Yes it doesn't make sense but using this approach will allow you to have your custom queries to access the module data and display options (transformations).
You have another option to create custom webparts for this and package them with your module but I'd recommend against this because it takes away from the basic usage of Kentico and will require code maintenance and modifications for simple changes.
If you look at page types you will see that Kentico does the custom page types to hold transformations. They have ones like RSS Transformations, E-Commerce Transformations, etc.
That is the way I have always done it also.
I suggest you to take a look at the custom table module as example, i.e. user interface part of it: there is transformation menu item under edit custom table in the interface. Take a look on how it is done and try to clone/modify it for your own custom module. If you check the DB: cms_transformation table has TransformationClassID field. So transformation is attachable to a class - so you custom classes can have transformations attached. Honestly i've never done it, but this is the way how I would approach. I would keep apples with apples, oranges with oranges... yeah sure you can always create "container page type" and it will work, but i would play around with the custom module. You might need to create and extender in this case.
#John,
As per Brenden post, you can achieve this using custom web part with your custom logic.

I need to use a custom control which is a simple navigation bar from another database
navigation bar is made with twitter bootstrap css framework,
why do I need to use a custom control from another database?
because this navigation bar is going to be common to four notes Databases,
how can I implement this more efficiently?, a control that is common to four databases
Domino includes template inheritance features that allow either an entire application or a specific design element (like a Custom Control) to be updated whenever the template design changes. You could link the shared Custom Control in each of your four applications to a common template so that, if you need to make changes to it, you only have to change it in one place. You can not reference a Custom Control that only exists in another application; you'd have to store it in each and link the design to keep it synchronized.
Alternatively, you can use the Extensibility API to convert it to a library component. Controls of this kind can be used in any application running on a server that has the library installed. A video tutorial for this process can be found here.
I have to work on a Drupal project to create user profile for some specific users on the website with some special fields. They can be a different role. Main idea is to search. User profile must be searchable with provided criteria.
I have two options,
1- Using node with (content_profile)
2. Create my own form and tables.
One my question is, is it possible to create a separate search machanism for custom created database? and is there a way to cache search result? or should I use node based? please advice some one with idea on this..
Thanks.
Yes it is possible to create a search mechanism using views and exposing the custom table to views via the api (there is a blog post here: http://blog.menhir.be/2008/10/22/expose-database-fields-to-views-in-a-custom-drupal-module/ and there is more info using the advanced help module (http://drupal.org/project/advanced_help) (install and look through the views documetation), then you could also use the Views caching.
A custom table and fields would be my preferred method if you have a lot of users as the profile tables can get pretty big (this may not be an issue for you), or you could use the content profile module http://drupal.org/project/content_profile and possibly save yourself some work!
If you wanted to perform a complete custom search not using views you'd probably need to implement that and the caching yourself if you went the custom field/table route, but you'd gain a lot of flexibility.
Or at least could anybody point me to docs about its crazy proprietary url parameters and html field name obfuscation? I can only suppose this is caused by SharePoint...
The main problem is, given a start page built with SharePoint, I can't recreate a form post with a programmative client because:
field names vary, they are appended with a some sort of id, hash, whatever (I think session.wise? Not sure)
tracing HTTP traffic on my side, I see the HTTP request is packed with strange parameters like __REQUESTDIGEST, __VIEWSTATE, and many others
Is this an intentional protection device put up by SharePoint? Which is the underlying architecture and which objects are involved (script callbacks, ... )?
(BTW, I'm not doing anything evil, just trying to extract public government data from a website).
Thanks.
SharePoint is nothing more than an ASP.NET Application, SharePoint completely Built on top of ASP.NET 2.0.
Being said that __VIEWSTATE is nothing but a Hidden Field that has the View State Information
Coming to __REQUESTDIGEST this is an Intentional Protection, this carries some sort of
securito validation which is called FormDigest
And finally to answer your Question, You will not be able to guess field and stuffs unless you have control to change the sourcecode of the application. Reason why the Name of the fields looks like obfuscated is because those controls are not handwritten but generated by the Code of ASP.NET Engine and parser, Reason field having such a name called Naming Container
One suggestion I would say is that, rather than trying to scraping the screen data, you can try alternate approaches, like each of the List in the SharePoint has the XML Feed inbuilt,try to consume it, if you have access to the site, try to retrieve the information using export to excel etc.
In addition to RSS, SharePoint also has a Web Services interface that you can use to get at and interact with data stored in SharePoint in a programatic way.
I've built a web part for Sharepoint that retrieves data from an external service. I'd like to display the items in a way that's UI-compatible with Sharepoint (fits in with its surroundings.)
I'm aware of the "DataFormWebPart" but was unable to get one working properly. It requires a valid DataSource and I was unable to build one from the results of a web service call... Part of the problem is that my web service wrappers don't expose the XML return info, rather I have a bunch of deserialized objects. There doesn't seem to be an easy way to turn actual objects into a datasource, or populate a "generic" datasource from object data.
I could use an SPGridView to get the same UI, but the grid control doesn't have much in the way of smarts -and- it forces every field into its own column. I'd prefer to render each list item as a single cell with complex rendering (for instance the way that StackOverflow shows its lists of questions.) I'd also like to get as much of the Sharepoint-standard UI as possible, such as the sorting, filtering, and paging controls.
So, first: Has anyone here written a Sharepoint control that does this, and if so do you have sample code to share? If not: am I overlooking some useful control, whether MS-supplied or available in an external library?
Thanks!
Steve
Sharepoint: Best way to display lists
of non-Sharepoint content with
“compatible” UI?
Take a look at the built in sharepoint web controls:
Microsoft.SharePoint.WebControls Namespace
It contains all the controls used in sharepoint. I'd tell you more, but the documentation is very thorough.
Problem with SharePoint is that there are a bunch of different ways to do this. If your data is not changing too often and is not overly large it may be worth considering entering it into a list for display.
If you have the Enterprise licence it may be worth getting your data into the BDC and using it there.
you may have to convert the objects into xml or use the serialised objects with the XML webpart for display. This still has the issue of custom rendering using XSLT.
Here's a great article that explains how to configure BDC connections to web services using the BDC Definition Editor:
Creating a Web Service Connection by Using the Business Data Catalog Definition Editor
http://msdn.microsoft.com/en-us/library/bb737887.aspx
The best way to do this IMO is to make a Web Part. As a Web Part the UI will be automatically rendered to be the same as the theme the site is using (unless you override it) and it will be able to be placed anywhere by anyone with admin privileges.
Tutorial on making a Web Part
Tutorial on packaging and deploying a Web Part
Example Web Part Source Code
You could create a custom web part and use an SPGridView. You say you don't like it, because it forces every field into its own column, but that's not true. You can create a template (ITemplate) for every column and fully customize what's shown inside it, just like you would using a normal ASP.Net GridView. Using this approach I've added the little "New" images right next to a list item's Title, just like SharePoint does itself.
