New Feature: Advanced SSO

06/23/2015 Posted by Brandon

We’ve released new features for advanced Single Sign-Ons, or SSO.

Our basic SSO options have been a big success – these allow users to log into Knack apps using other common accounts they already have with Google, Twitter, and Facebook:

We’ve added additional advanced SSO options so you can create additional login options.

Here’s how it works: there are two common login technologies (oAuth and SAML) used for authenticating logins. You can add any custom login that uses one of these two.

For example, you could add logins using SalesForce or LinkedIn with oAuth. SAML enables more enterprise configurations like Shibboleth and Active Directory.

Adding a custom login

To add a custom login you can use the “add a custom SSO provider” link in the Login view’s “Options” tab:

You’ll be guided through configuring the login with the right options. There’s a lot of options to configure so you may need a developer to help get them all correct.

You can also customize the login button with a color and logo. Here’s a customized LinkedIn login button:

Domain Limiting

In addition to adding new login options, both the Google and OpenID SSO providers have an option to enforce domain restrictions. This means that you can provide a domain to restrict authorization to. Only accounts with emails from that domain will be authorized.

For example, by entering “” with a Google SSO, only Google accounts with an email address using will be authorized.

You can find the full details in our support article on logins:

We also added a recipe to our cookbook for adding a LinkedIn login:

Pricing Note: these advanced features are available on Corporate plans and above, or with an add-on to the Pro plan.

New Template App: Attendance Tracker

06/15/2015 Posted by Brandon

One of the most common app questions we get is if Knack can handle different attendance apps:

  • Schools taking class attendance.
  • Churches managing small group attendance.
  • Corporations taking attendance and roll-calls for trainings and meetings.
Attendance apps sound simple but can quickly get complicated. How are you reporting attendance? Who’s in charge of taking attendance? Are you recording any additional information? Maybe you want to track each member that attended and if they brought any visitors.

Knack shines in building custom attendance applications like this where you need to tailor your attendance around specific needs.

We recently built a new template app to show a few examples of how attendance can work.

API Upgrades: Working with logged-in users

06/02/2015 Posted by Brandon

We’ve added some new features to our API so that you can now make login requests and work with the logged-in user!

Highlights include:

  • Secure user tokens to authenticate request for Knack users.
  • Utility functions for getting properties of the logged-in user and checking for role permissions.
  • Remote login requests.
This opens up a lot of great possibilities for developers to work with Knack apps:

  • Mobile developers can have mobile users log-in with their Knack credentials.
  • Make page requests with views that are connected to the logged-in user.
  • Permission customization with user roles.
We’ve include an article in our API documentation that goes into more details:

Case Study: More baskets for your database eggs

05/28/2015 Posted by Brandon

Joshua Guy Lenes replaced a custom-programmed database with a Knack solution so more team members could help build and maintain it.

Joshua Guy Lenes is familiar with complex, custom database solutions. He works with the American Association of University Professors to manage union memberships. They used to employ a custom-engineered database coded in python, django and sql.

It was a suitable system but there was one big problem: Josh, a trained and capable developer, was the only person who knew how to manage the database and keep it running smoothly. It was too complex to easily bring on others to help.

He knew this would not be sustainable in the long run — if Josh somehow became unavailable how would the system be maintained?

Josh needed a more flexible database solution that his team could easily use and manage without his assistance, and the search began for a replacement.

Recent Upgrades

05/20/2015 Posted by Brandon

Even though everyone loves big new features, most of our favorite upgrades are often to existing features — little tweaks that improve performance or add functionality.

We recently completed a round of smaller upgrades and wanted to post about them.

Submit the current location of the user

You can now add a Form record rule to set the value of an address field to the user’s current location:

Note: this option is only available on Pro plans and above.

Separate time defaults

For Date/Time fields you can set separate default values for the time component:

Default menu tabs

Format menus to work like tabs and start with the first menu link selected:

Empty tables

Format a table to hide any columns where every column value is empty or blank:

Yes/No Feature Upgrades

05/11/2015 Posted by Brandon

We’ved added some new input options for a Yes/No field:

You can now choose from the following inputs to display the field in forms:

  • Dropdown
  • Radio Buttons
  • Checkbox

The checkbox display has an additional option for text to display by the checkbox:

This is a great option for adding “agreement” inputs where you want the user to check the box before proceeding. You can use a special text field (from the “special” tab) above the checkbox, and set the Yes/No field to required:

Case Study: Medical Healthcare Network Solutions

04/24/2015 Posted by Brandon

When MHCNS first looked at Knack they simply wanted an internal data management solution. What they found was a comprehensive application platform that is expanding their revenue and growing their business.

MHCNS enjoying their success!

Early in the summer of 2014 Josh Cameron was researching online database systems for his employer Medical Healthcare Network Solutions, a Houston-based provider of tech services for medical-based businesses and private practices.

He needed an internal data management solution — something that could cut through all the spreadsheet confusion and bring clarity to their projects and clients.

A article about online database tools led Josh to give Knack a try.

He quickly got a sense for Knack’s potential and built a comprehensive company portal including project management, a knowledge base, and equipment tracking.

“We had hundreds of excel sheets that were wasting so much time”, Josh explained. “Our clients were constantly contacting us with the same issue. Knack has allowed us to reinvent ourselves as a company. We have less paper, spreadsheets, and confusion. This has allowed us to have more clients, revenue, and efficiency across the board.”

This would be a great Knack success story if it stopped there. But it gets better!

A little more than 6 months later, MHCNS started hiring staff to round out an entire department devoted to building web applications on the Knack platform.

How did Knack go from meeting an immediate data management need into helping develop an entirely new profit center?

New Feature: Page Pop-ups

04/21/2015 Posted by Brandon

You can now choose to display specific pages as pop-ups.

This is perfect if you have a table and want to quickly view more details about each record. Instead of viewing those details on a new page and clicking “back” to refresh the table, you can now view them in a pop-up:

To set this feature simply click on the page in your interface and the “Page Options” link in the right column:

And enable in the “Edit Page” window:


  • The popup only works on the designated page. Any further links to other pages will return to the main window.
  • The popup will only work if navigated to from another page. The page will still display in the main window if it’s the first page the app loads.
  • This is in beta so let us know if anything is off.
See, not all pop-ups are annoying!

Report Upgrades

04/14/2015 Posted by Brandon

A major goal for 2014 has been an upgrade to our Reports view.

We originally released reports a few years ago and they’ve been looking dusty for a while now. At the time we were content to use a Google Charts library with some basic functionality.

Since then our wonderful customers have helped us compile a giant list of improvements to make and we’ve found a great new chart library. The first wave of these upgrades is now ready!

Better Chart Rendering

The new chart library means improved chart rendering that animate into place and have clearer graphics and numbers:

You can hover over the plot points for more information and click on any group in the legend to show or hide that group from the chart.

Larger charts will also auto-resize to better accomodate the available data.

Visual Customization

We’ve added multiple features for controlling the size and layout of the charts:

  • Dimensions: let the chart auto-size or enter your own width and height.
  • Legend Placement: place the legend at the right or bottom.
  • Orientation: flip the axes of bar charts.
  • Data Points: show or hide
  • Tilt Data Labels: to save more space

New Data Features

Our biggest new features are around the data the reports use:

  • Filters: you can now use filters to limit the records the chart uses, including filter menus and user-defined filters.
  • Exclude Empty Groups: if any of the report data is empty or zero you can choose to exclude it from the report.
  • Allow Print and Export: include links to print the report or export it as a PDF.
Expand Group Records

The best new feature is the ability to click on any of the report groups to view the records that comprise that group in a modal page:

This page will limit any records to the report group, but you can add and customize your own views like any other Knack page!

What’s next?


  • Better sorting and limits.
  • Better mobile resizing.
  • A new chart type!
  • More customization and advanced report chart features.
Take a look at your reports and let us know how the new upgrades look!

Databases through the eyes of a 10 year old

04/09/2015 Posted by Steve

Video games: the perfect 10-year old treasure trove of data

Meet Mason, he is 10. He is an avid reader of reference books, a video game junkie and a professional database builder. Ok, maybe not a professional…yet.

But his dad is. That's me, Steve. Knack customer success agent and database builder by day, soccer dad and zookeeper by night.

Stats and data have always been an area of deep interest for Mason. Ever since he was able to read and write, he has enjoyed creating his own reference books. Books may be stretching it; more like sheets of scrap paper about video game characters stapled together, but you get the idea.

Being the son of a parent in the tech space, there was never any doubt technology would play a big part in his life. So to channel his inner nerd, I thought it might be fun for him to build his own web app and online database.

Working for Knack, it seemed like this would be a perfect opportunity to introduce my son to the company I work for and, since Knack is perfect for creating reference databases, give him the ideal toolkit to take his own reference “publications” to the next level.
