Build beautiful and interactive API documentation for ORDS

Image
In this blog post, I will show you how to quickly build beautiful and interactive API documentation for your Oracle APEX REST data sources using  swagger hub . Using APEX v23.1. I downloaded the  titanic data set  and loaded them into tables in my APEX instance, created some authorized restful services and published them using swagger hub. You can create a free account on swagger hub.   Check out my titanic swagger hub here ; Press Authorize. Username REST, password Glasgow123! I won't go through creating RESTful services and just show you the four I created that sit on top of the titanic data set; The GET is a very simple SQL query;      select * from TITANIC_DATA_SET_NEW A handy tip is to add comments, as there will appear on swagger hub, making your API self documenting; Once you have created your modules, press the Generate Swagger Doc button; This will generate an open API for you.  Copy the API and paste it into swagger hub This will generate the documentation; As mentioned b

APEX Office Print

Image
This post is how we used APEX Office Print (AOP) in the University of Glasgow in Scotland to print APEX forms and loved it 😃 The app The application is a Performance Development Review (PDR) APEX application for staff at the University of Glasgow.  There are 7,000 staff and several different forms depending on the staff role.  A professor will get a different form to a Janitor for example. CSS Print Our first attempt at printing was using a print style sheet.  This worked to a certain extent but we had major issues printing Interactive Grids and you dont have a great deal of control over what gets printed especially as we had several different APEX forms. Apex Office Print to the rescue We purchased AOP on-prem  bronze  and its paid for itself in the year we have been using it as we have went from dozens of print queries where we were constantly updating our print CSS to zero queries (yes zero!!!).  The resulting word documents the users now download are also much more professional lo

Oracle APEX Interactive Grid colour cells based on a condition using JavaScript and CSS

Image
In this post I will describe how to colour an Interactive Grid based on a column condition using CSS and JavaScript.  Using APEX Version 19.2. I want to colour every column red in my IG when the value is 'No'.   I have several IGs on my page I want to colour, so I set all my IGs that I want to colour with a CSS class of ATTENDEE_SCORE_IG in the Appearance section of the IG; Every column I want to colour in the IG I set the CSS Class to COLOUR_YES_NO (in this example I set this in 5 columns); I then created a Dynamic Action (DA) that contains the JavaScript that has the condition check that will colour the cells.  Because I have several IGs that are details of the master/detail relationship and these are refreshed by the user clicking on the master detail IG I have made my DA a Page Change [Interactive Grid].  If you don't need this you can set the DA on page load. The JS which will colour every column is this; ////////////////////////////////////////////////////////////////

Oracle APEX style an Interactive Grid cell conditionally based on the value of another cell using JavaScript and CSS

Image
This blog post describes how you can style an Interactive Grid cell conditionally based on the value of another cell using JQuery and CSS.  Using APEX Version 19.2. The requirement is to highlight the cell that has the highest value in the row; This can be achieved by setting the IG column CSS class and using JQuery to loop round the table rows to conditionally set CSS style based on cell values First give all your columns a CSS Class (note you can give columns multiple classes separated with space) in this case all 4 columns are set with CSS class SCORE_C_1, SCORE_C_2, SCORE_C3 and SCORE_C_4 in the column Appearance; We now add the JavaScript in Execute when page loads (preferably put this is a JS file). We are using the JQuery $.each() method to fetch every table row;  $.each($('tbody tr'), function(i, item) {} and the JQuery text() method to get the column value from the row using the column CSS class names;         var scoreC1 = $(item).find('.SCORE_C_1').text();
