Within my django application, I have designed a page featuring a button that controls the operation of a clock. Initially, the page displays only the button, with a hidden form where users can input details such as their name and description. When the button is clicked, the clock begins to run. Subsequent clicks on the button will stop the clock and reveal the previously hidden form.
To achieve this function, I utilized JavaScript to assign a status value of 'start' or 'stop' to the button. A function is then used to analyze the button click and update the status accordingly.
var buttonStatusChange = function(){
var buttonstatus = $('#clockbtn').attr("value");
if (buttonstatus == "start"){
$('#clockbtn').attr("value", "stop");
...
hideElement("userinputdiv");
} else if (buttonstatus == "stop"){
$('#clockbtn').attr("value", "start");
...
showElement("userinputdiv");
}
};
var showElement = function(elementId){
var elem_selector = '#' + elementId;
$(elem_selector).show();
};
var hideElement = function(elementId){
var elem_selector = '#' + elementId;
$(elem_selector).hide();
};
In the backend of my Django view, I am ensuring the validation of the userinputform and other forms during a post request. If validation fails, the form is displayed again with error messages next to the relevant fields.
def my_view(request,...):
if request.method == 'POST' and otherform.is_valid():
...
userinputform_is_valid = userinputform.is_valid()
if not userinputform_is_valid:
return custom_render(request, context, template_name)
...
# extract values from form, save, etc.
def custom_render(request, context, template):
req_context = RequestContext(request, context)
return render_to_response(template, req_context)
Here is the HTML snippet for the page:
....
<div id="userinputdiv">
....
<form ...>
<p>
<span id="myfield">Enter WholeNumber:</span>
{{my_form.myfield}}{{my_form.myfield.errors}}
</p>
...
Unfortunately, due to the CSS rule that hides the userinputdiv, validation errors are not visible to the user. Though the errors exist within the page source code, they are not displayed. I am contemplating how to address this issue, as I want the form to be visible only if there are validation errors, and not by default when the clock is not in use. This is crucial as the clock data is utilized as hidden fields within the form for further processing in my Django view.
