Now available : Data aggregation in list/chart views, Data-access & Caching functions and more..

Over the month we have rolled-in the following features in your free online database app builder and free online crm, built over Google App Engine for use with Google Apps.

1. Data aggregation in list views & chart views
2. Data access and Caching functions
3. Search for files to attach from Google Docs

Data aggregation in list views & chart views

Numeric attributes (integer and float types) can now have a Default Aggregation configured to display the sum of the fields' values in the list views and in the chart views.

In our iFreeTools CRM, our free CRM app for use with Google Apps, we have enabled this for fields in Expected Revenue, Budgeted Cost and Actual Cost fields in Campaigns and for Amount and Expected Revenue in Opportunities.

The summation of the values from such fields will be listed below the list view as shown in the image below..


Along with this we have also enabled the result of aggregation from multiple attributes to be rendered in the same graph, so that you can compare related aggregation values visually.

The following image shows the chart views for Campaigns enabled to display values from 3 attributes, Expected Revenue, Budgeted Cost and Actual Cost, grouped by Campaign Status..


For your custom online database apps, built over iFreeTools creator you can specify this configuration in the Attribute form, when you add/edit the attribute details.

Note : All aggregation / charting features are currently restricted to work with smaller batch of data. When our Scheduled Reports feature is available, you can create summary / charts for full set of data.

Expressions for Computed Formula Fields & Field Validations, now available in iFreeTools

The labs setup of the Google App Engine powered free online database apps creator, now has support for defining and using expressions for calculated formula fields and in validations.

Update : it is now available at http://creator.ifreetools.com too.

Note : When adding new formula expressions, you will need to re-index the existing records to have the formula value computed for those entries.

Formula Expressions

You can now define expressions based on values in other fields in the database record to compute the value of formula field.

For example, you might have First Name and Last Name as fields within your database record and may prefer to have them combined in another Name field. For this you can add the 3 attributes with data-type as Single line text (String) and for the Name attribute you can set the Formula Expression (under Advanced section of the attributes form) to be

val("First Name") + " " + val("Last Name")

The val function enables you to fetch the value of the field for a given display name.

The formula expressions can be set for any data-types, just make sure the return value of the expression is of the required type.

Aliases for fields

You can also set Aliases for the attributes and use them instead of the val functions, to have the formula to be something like

First_Name+" "+Last_Name

Validation Expressions

You can also define validations expressions which need to evaluate to True for the record to be stored into the database.

So, if you have a product code field and it should always be 5 characters in length, you can set the Validation Expression as

len(inputValue) == 5

For more details on the operators and functions available for use within expressions, kindly refer to Using Expressions for Formula-fields and Validations, in our user guide.

Yes/No (Boolean) fields support in Custom Views and more

We have been making improvements over the past few weeks to the Free Online Database App Creator for use with Google Apps and in our Free CRM built over Google App Engine, based on feedback/suggestions from our users.

Filter based on Yes / No checkbox (Boolean) fields

We are glad to have rolled in support for Custom Views which can filter records based on Yes / No checkbox (Boolean) fields.

Apart from Yes or a No, you may now also see a --not-set-- value for fields which do not have a value already set for that field. This can happen in iFreeTools Creator, when you add a new Yes / No checkbox (Boolean) attribute to an existing entity which already has records in database. While the new records will have values for this field, the older records will show a --not-set-- value.

The records with --not-set-- value *will not* turn up in the results if the filed is used in the filtering criteria for that Custom View. If you would like it to be available, you can use the bulk-edit to set the values for that field to either Yes or a No.

Customize the order in which the Custom Views are listed

We have also added support customizing the listing order of Custom Views based on View Listing Index value, which you can now provide in the Add/Edit Custom View form. The views will be listed under the module based on this value, in ascending order. That is, views with smaller View Listing Index value will be listed first.

And more..

Apart from these features mentioned above, we have also rolled in a few bug-fixes/improvements, including in the recently added Calendar Views feature.

What's Cooking : Calendar Views in your Online Database for Google Apps

Yes, support for Calendar Views is what is cooking up at iFreeTools and it is already available in our labs deployment : iFreeTools Labs.

All records which have a date or a date-time field will now have an option to view the records in a Calendar View as shown below..



The calendar view will have options to view the records based on Month, Week or Day. The details view is also loaded via AJAX, as shown below, without you having to leave the calendar view.



The feature will be rolled into your affordable CRM for Google Apps and your favorite custom database app builder for Google Apps, in the coming days.

The current feature uses any one date/date-time field, at a time, for the Calendar View. We will be coming up with an option to specify start & end fields too, so that you can have the events span across hours and days too. And together with that you will have an option to export the data to Google Calendar in iCal format.

Hope you like the new feature. Do keep sending in your valuable suggestions.

Alphabetical indexing of database records for Quick filtering, now available in iFreeTools

We have just made an upgrade to our online database app creator and our online CRM apps, which have been built over Google App Engine for use with Google Apps.

This upgrade adds support for alphabetical indexing of database records and index links for quick filtering from the list views.



This has been enabled for the relevant fields in our default CRM application. For custom database applications built over iFreeTools Creator, you can enable them for String and Reference attributes, by editing the Attribute and selecting the indexing option, as shown below..



Multiple attributes can be configured to be indexed and they will all be available for filtering from the list views. If there are more than one alphabetical index, you will find a more.. button which you can click to view all filtering indexes.

For existing records (added to the database, before enabling the index), you will have to perform a re-indexing operation once, from under the list views More Actions > Re-Index.

Hope you find the new feature useful. Keep sending in your suggestions.

Attach Google Docs to Database Records in iFreeTools CRM & Creator

Our CRM for Google Apps and Online Database App Creator for Google Apps now support attaching of Google Docs to the records within the database.

Update : We have upgraded this feature to support attaching any file / folder from within Google Drive. More details are available in this blog post : Attach files or folders from Google Drive to your database records.

Below the record details in the details page, there is now an option to attach a file from Google Docs. When you click on the Attach a Google Document button, you will be required to authorize the Google Docs account to use, this can be a Google Docs account associated with either Google user account or with a Google Apps user account.

After authorization you can view the list of files in that Google Docs account, with details like the file name, file type and the person who last modified it as shown in the image below..


Just click on the attach button and the file will now be linked to your database record.

All such attachments will be listed below the record details, as shown below..


Attaching a file in Google Docs does not duplicate the contents, but directly links to the document in your Google Docs, making sure the latest doc can be accessed from the record.

The security settings set in the Google Docs are still applicable and you need not have to duplicate those setting again. When someone clicks on the attachment link, they are taken to Google Docs directly which handles the security settings.

Update :When attaching files from Google Docs to your records, you now have the option to search for the required file based on text, to narrow down the files and attach the required file to your record, as shown in the image below.

Hope you find this new feature useful. Keep sending in your suggestions.
