In DotCMS, can we pull data for content from external database instead of dotcms database and display?
I created new content type as Text with two fields. 1) KEY field with type text and 2) VALUE field with type text.
When I try to add new content type, it should pull data directly from external database Adding content or updating the content also should go to external database. Is there any way to do this?
This is not how dotCMS was designed to work. dotCMS expects content to be stored in dotCMS. It would be possible to implement pre- and post hooks against the contentlet API that would intercept the store and retrieve calls to push and pull content from an external source when content is added/modified/deleted in dotCMS, basically keep an external source in sync.

Any resources on how I can create a csv file uploader on APEX which previews the data on an interactive grid for editing and changing data before uploading to a table?
Loading the csv:
Create a data load definition in shared components for your file, target type table. Create a table for this in which you'll temporarily store your data.
On the page, create a file upload item
In page processes, create a process of type Data Loading, use Data Load definition from step above.
Previewing the csv
Create an IG region on the table you use in Data Loading config.
When preview is complete, copy the data in to the actual table.
That is the raw outline of what you need to do, I left out the details. But there are plenty of resources on how to do each step avaiable on the web.
We are building a Sitecore site that will pull in some product data from an external database. On a nightly basis we will query the external database and either Add, Update or Archive/Delete/Remove product content items in Sitecore as needed. Our data template has some fields that will be populated directly from the external database (and will be read-only for content authors) and other fields that they will populate themselves. Included in our custom fields will be the SKU of the item from the external database. It is possible that over time a product could disappear from the external database. In this case we would want Sitecore to somehow remove this item from our list of products, but not completely delete it. The reason for this is that the products that have been removed could reappear in the future and we would not want to lose all of the data that had been added to other custom fields on the item. I can think of a number of different approaches for this:
Use Archiving/Recycling features of Sitecore. When we find that there is a product item in Sitecore that no longer appears in the external database, then we could archive it. That works well. However I can't seem to figure out a way to restore that item later if it reappears in the external database. I don't have any access to any custom fields when an item is archived (from what I have read online). So when I come across a SKU in the external database that is not in Sitecore, I have no way of figuring out if there is an archived item that has that SKU.
Use a custom status field on each product content item. I could set each product content item to "active" or "inactive". This would make it easy to reactivate items that reappear in the external database. However I worry about things like search and publishing. It seems messy to me to have some content items that are inactive in the folder of all products in the master database. It could be confusing to content authors and I worry that they will find their way in to the web database, etc. It seems like I would have to do a lot of custom coding to make sure that those products do not show up on any pages, etc.
When a product disppears from the external database I could then move those content items to a different location in Sitecore. Then when they reappear I could move them back. This also feels messy.
I just wonder if there is some better solution that I am missing. Thanks in advance for any help.
I would go with option 2 "Setting status field on each product "Active" or "Inactive", as its more clear and keep the data in one place.
Additional thing to do (as suggested by Vasiliy) is to set the "Publishable" checkbox on product to "False", this way the product will disappear from web database, hence no extra filter in your search methods.
You can implement custom content editor warning to inform content editor that the current product is "inactive":
Creating Custom Content Editor warnings
Hope this helps
Just a thought what if you just unpublished the items that were removed from the external database and set the ones in the authoring db unpublishable until they reappear again. With this scenario, you could also have a task running archiving items that have been unpublished and not republished for a given period of time.
The best solution really depends on the number and frequency of items appearing / disappearing and the cost benefit of keeping those items in the authoring database vs. deleting them.
How do bind a DropLink using a custom dataprovider?
More info:
I am trying to build a product catalogue site using Sitecore. Each product in the sitecore content tree can have a star rating and short text review attached to it (which will be linked to a user extended with a profile provider but that is another question).
I am planning to store the review information in an external database and reference it using a custom dataprovider. I have downloaded the NorthwindDataProvider from the Shared Source (here) and have altered it to use a table which contains the rating, text and a uniqueidentifier field to store the ID of the product from in sitecore the review is attached to.
The template field is a droplink and the datasource is set to the products in the catalogue.
When I edit a review in the custom dataprovider using the sitecore content editor, the droplink states 'Value not in selection list' even if I select one of the populated products and save using sitecore.
It is saving the ID in the database but if I look at the raw value it displays the id without the curly brackets. Working droplink fields' raw values appear to contain the brackets.
To create a review, I am using a jquery post to a webservice which writes to the database using an external datacontext. Should I be using some Sitecore API to use the custom dataprovider instead?
Any information using custom dataproviders would be helpful. The documentation I've been able to find has all stated what can be done but I'm struggling to find actual implementation.
So the first thing is that you have a template field and you're using droplink which is going to store the guid for the item selected. I'm not quite clear on whether or not you're pointing the datasource to a Sitecore item or not.. but that's essential if you're using droplink. Here's what I would suggest instead for the most straight forward way to do this:
Create a template that you add fields to handle the logic dealing with your catalog items. How you do that is your choice and Sitecore doesn't care since its only going to deal with the item and all it cares about is finding an item... you write business logic to manipulate the external data.
Once you have a folder that stores your catalog items, you could easily write a script to be triggered by the Rules engine in Sitecore or a Sitecore task that runs regularly to get your catalog items to add/update or remove the corresponding list of Sitecore items.
Also, another option that is more complex to implement, but if you have multiple data sources on your site, is a valid approach, is to use an object framework (like the Entity framework) as a data object layer that allows you to create and populate common objects with from any data source.
Hope this is helpful!
I am working on a project that needs to be able to create dynamic queries into an H2 database. This also includes a full text search with built-in H2 logic, tables, and triggers.
I have been trying to figure out how to add that full-text search into my CriteriaQuery but keep running into the road block that the tables used aren't entities in my model. I could add them as entities, but I don't want them created automatically by EclipseLink when a new database file is created since there is a function in H2 that creates the tables and does other necessary housekeeping.
I had tried the path of creating a view to query the full text tables to give me the information I need in the format I need. But I still keep running into the same problem that that view is not an Entity.
Has anyone encountered this situation before and/or figured out a way around it?
Thanks!
This is my scenario: I need to copy files to a sharepoint document library using its web services and set metadata on them. That's all possible with CopyIntoItems (from Copy webservice) except for Lookup fields. CopyIntoItems ignores them, so i need another way to set data on those fields.
I've tried to create a list item with the mandatory and lookup fields metadata and then, using the item ID (creating a FieldInformation field with the ID, as well as some other simple metadata), called the CopyIntoItems method and, instead of updating the item, sharepoint created a new one.
I can't do this in the reverse order because i have no way to get the ID from the item created by CopyIntoItems...
So, the question is: How can i upload a file to a sharepoint document library and set all its metadata? Including Lookup fields.
Use a regular PUT WebRequest to to upload the document into the library
Query the document library to find the ID of the item you just uploaded (based on path)
Use the Lists.asmx web service to update the document metadata
Helpful link: Uploading files to the SharePoint Document Library and updating any metadata columns
Keep in mind that if the destination folder item count + the ancestor folders item count exceeds the list view threshold then you can't query the list for the id (step 2 from Kit's answer).
Queries can be done more efficiently if constrained to a particular branch in the folder hierarchy. A workaround would be to modify the site settings, but the queries would be sluggish and would make the solution less portable because the threshold for Office365 and BPOS can't be changed.
