Module Builder -> Updating fields programmatically

Posted by Community Admin on 20-Feb-2012 00:00

Hello,

I am trying to update a value of one of my custom module data rows. I am following the code set out via the examples provided with the custom module page. However, the following error occurs:

Cannot publish an item that is not a master.

This is very confusing. I have tried a number of methods to get around this, but none seem to be working (for example, I get a similar message but with 'temp' instead).

Can you provide me with a solution to this problem?

Thanks,
Rich

Hi,

I have created a dynamic module with the name "Tito" (used a strange name here). This cretes new item for this module with :

DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();

Type titoType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Tito.Tito");

DynamicContent titoItem = dynamicModuleManager.CreateDataItem(titoType);

// This is how values for the properties are set

titoItem.SetValue("Title", "Some Title");

titoItem.SetValue("Owner", SecurityManager.GetCurrentUserId());

titoItem.SetValue("PublicationDate", DateTime.Now);

// First we will publish the item

dynamicModuleManager.Lifecycle.Publish(titoItem);

After this I get the item Checkout the item and change the value with SetValue

dynamicModuleManager.Lifecycle.CheckOut(titoItem);

// We can now change any values of the item

titoItem.SetValue("Title", "Checked out item");

// Now we need to check in, so the changes apply

//titoItem.Lifecycle.(titoItem);

//Finnaly we publish the item again

dynamicModuleManager.Lifecycle.Publish(titoItem);

// You need to call SaveChanges() in order for the items to be actually persisted to data store

dynamicModuleManager.SaveChanges();

To use SetValue you will need using Telerik.Sitefinity.Model;

The full code:

DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();

Type titoType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Tito.Tito");

DynamicContent titoItem = dynamicModuleManager.CreateDataItem(titoType);

// This is how values for the properties are set

titoItem.SetValue("Title", "Some Title");

titoItem.SetValue("Owner", SecurityManager.GetCurrentUserId());

titoItem.SetValue("PublicationDate", DateTime.Now);

// First we will publish the item

dynamicModuleManager.Lifecycle.Publish(titoItem);

// Then we check it out

dynamicModuleManager.Lifecycle.CheckOut(titoItem);

// We can now change any values of the item

titoItem.SetValue("Title", "Checked out item");

// Now we need to check in, so the changes apply

//titoItem.Lifecycle.(titoItem);

//Finnaly we publish the item again

dynamicModuleManager.Lifecycle.Publish(titoItem);

// You need to call SaveChanges() in order for the items to be actually persisted to data store

dynamicModuleManager.SaveChanges();

I'm having a similar issue, I'm getting the same error. I can't get it to update a record. Creating one is fine, but I need to update a record. This is what I have:

DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();

Type productType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Recipes.Recipe");

DynamicContent c = dynamicModuleManager.GetDataItem(productType, this.ID);

if (c != null)

try

// first we check it out

dynamicModuleManager.Lifecycle.CheckOut(c);

// We can now change any values of the item

c.SetValue("Votes", this.Votes);

c.SetValue("Rating", this.Rating);

// Now we need to check in, so the changes apply

dynamicModuleManager.Lifecycle.CheckIn(c);

//Finnaly we publish the item

dynamicModuleManager.Lifecycle.Publish(c);

// You need to call SaveChanges() in order for the items to be actually persisted to data store

dynamicModuleManager.SaveChanges();

catch

return false;

return true;

This works, but it doesn't publish:

DynamicModuleManager dynamicModuleManager = DynamicModuleManager.GetManager();

Type productType = TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Recipes.Recipe");

DynamicContent c = dynamicModuleManager.GetDataItem(productType, this.ID);

if (c != null)

try

// first we check it out

// We can now change any values of the item

c.SetValue("Votes", this.Votes);

c.SetValue("Rating", this.Rating);

// You need to call SaveChanges() in order for the items to be actually persisted to data store

dynamicModuleManager.SaveChanges();

catch

return false;

return true;

Any thoughts?

Have you checked out this article? ( =

docs.sitefinity.com/for-developers-edit-content

I believe you should create a temp var to store what you are checking out, make the changes and then check in that temp var:

        // first we check it out
        var tempItem = dynamicModuleManager.Lifecycle.CheckOut(c);

        // We can now change any values of the item
        tempItem.SetValue("Votes", this.Votes);
        tempItem.SetValue("Rating", this.Rating);

// Now we need to check in, so the changes apply
dynamicModuleManager.Lifecycle.CheckIn(tempItem);

        //Finally we publish the item
        dynamicModuleManager.Lifecycle.Publish(c);

        // You need to call SaveChanges() in order for the items to be actually persisted to data store
        dynamicModuleManager.SaveChanges();

Hope this helps!
