🚀 Jam.py v7.0.114 is Here: Jinja2 Support, Multi-Field Search & Mobile-First Teaser!

[Danijel Kaurin]

Hello Jam.py Community,

We are excited to announce the official release of Jam.py version 7.0.114!

This release brings significant performance improvements, enhanced templating flexibility, and handy developer productivity features. Here is everything new in this update:

🌟 What’s New in Version 7.0.114

1. Modern HTML Templating with Jinja2

Jam.py V7 now leverages the Jinja2 library for handling custom HTML page variables.

• Why the change? Previously, percentage signs (%) in custom CSS rules could trigger app crashes during template dictionary parsing. Jinja2 eliminates this issue entirely, giving you faster page loads, greater reliability, and full access to modern templating features.

• Action Required: If you use custom login.html, register.html, or other custom template pages, please update your variable syntax:

<!-- Old Syntax NOT WORKING ANYMORE-->
<input type="text" class="form-control" name="login" id="login" placeholder="%(login_text)s" value="%(login)s">

<!-- New Jinja2 Syntax -->
<input type="text" class="form-control" name="login" id="login" placeholder="{{ login_text }}" value="{{ login }}">

2. Multi-Field Typeahead Lookup Search

You can now configure typeahead lookup fields to search across multiple fields simultaneously!

// Example: Search employee records by first name, last name, or email address
function on_edit_form_created(item) {
    item.employee_id.enable_typeahead = true;
    item.employee_id.lookup_search_fields = ['first_name', 'last_name', 'email'];
}

3. Modernized Default HTML Templates

We separated the HTML templates for the App Builder and the Default App Login, introducing sleek, modernized interface templates out of the box.

4. Modern Input Button Layout

Upgrade your form field aesthetic! You can now enable a clean, modernized layout for input field action buttons.

• How to enable: Navigate to your Project Parameters and check "Modern input buttons".

5. Builder Search Filters & Bug Fixes

• Tab Search Filters: Quickly filter through events, task items, and item fields directly inside each tab pane of the App Builder. Note: in task tab --> search for task tree works only for item level nodes

• Fixed several minor issues in the App Builder for a smoother development experience.

6. Jam.py now has 20 bootstrap themes for the UI!

🔮 What’s Next for Jam.py?

We are actively developing a mobile-first application experience:

• Mobile Cards & Bottom Sheets: Replacing dense data tables with responsive card views and traditional modals with sleek bottom-sheet forms.

• Native PWA Support: Transform your Jam.py web apps into fast, installable Progressive Web Apps.

• Custom Jam Datepicker: Replacing the Zebra date-time picker with our custom-built jam-datepicker plugin.

• New UI Plugins: Dedicated extensions including Kanban boards, photo galleries, and more!

Stay tuned—a live demo of these mobile features will be available soon!

Hi Fabio,

If you mean from a previous v7 jam application, I've only changed the custom code on my custom login.html page, that's all.

If you mean from a previous v5 jam application, I've converted my application in stages with the first stage doing the steps as explained in the documentation: https://jampy-docs.readthedocs.io/projects/V7/en/latest/how_to/how_to_migrate_to_v7.html

Regards,

Manos

Hi Manos,

I didn't explain myself clearly.

I have an older version of Jam7 on my PC.

I created an application using that version.

I'd like to upgrade everything to version 114.

Here's what I would do:

1. Back up my application (Export to zip)
2. Update Jam (pip install --upgrade jam.py-v7)
3. Restore the application

Are these the correct steps?

thanks

Ciao

Fabio

Hi Fabio,

Since your application already uses Jam v7, you do not even to export/import it.

I simply stop my v7 applications (e.g stopping apache), update jam v7 on the venv I use (using pip ) and then simply restart the application server (apache).

The only thing that requires manual actions is if you are using custom login or html pages that use system variables; these need to be changed to use the new syntax as explained here:

<!-- Old Syntax NOT WORKING ANYMORE-->
<input type="text" class="form-control" name="login" id="login" placeholder="%(login_text)s" value="%(login)s">

<!-- New Jinja2 Syntax -->
<input type="text" class="form-control" name="login" id="login" placeholder="{{ login_text }}" value="{{ login }}">

That's all you have to do.

Best regards,

Manos

[Fabio Lenzarini]

many thank, work!

Is the image management working properly for you?

[Danijel Kaurin]

Hi Fabio.

I fixed this. Please upgrade the package.

Thanks, now work fine, but I can't see a "delete" button to empty the image.

I can only change the picture.

ciao

Fabio

[Danijel Kaurin]

Hi Fabio,

I'm afraid you need to implement that logic within your application, as that option is not included for image fields in Jam's core.

Regards,

Danijel

[Dean D. Babic]

HI Fabio,

this is actually documented, the image is deleted with pressing CTRL and double-click on the image:
https://jam-py-v7.github.io/jampy-docs-v7/intro/tutorial02/index.html
"To clear an image, hold down the Ctrl key and double-click the image."

Not sure how to do that on a mobile phone tho :)

Cheers

[Fabio Lenzarini]

Thanks Dean
