RE: [web2py] Displaying only certain fields of choice with SQLFORM(...) update

2020-01-28 Thread John Bannister

If you don’t want the field to be displayed in the SQLFORM() you need to set as 
follows:

db.table.fieldname.readable = db.table.fieldname.writable=False before the form 
initialisation.

 

So something like :-

db.dog.owner.readable=db.dog.owner.writable=False

form = SQLFORM(db.dog)

if form.process().accepted:

…..

….

return dict(form=form)

Look in the docs

in your controller before showing your form,

db.yourtable.yourfield.readable=False!!!

[web2py] Displaying only certain fields of choice with SQLFORM(...) update

2020-01-28 Thread mostwanted

I was wondering if there is a way to show the SQLFORM() with only certain 
fields for the user during a form update & not show all the fields. 
SQLFORM.grid(...) has the field=None argument which enables one to select 
the fields to be displayed in the view, is there something like that for 
SQLFORM()?
I have some fields which only do calculations in my db tables & those are 
the fields I wanna hide during updates.

I haven't looked into that feature (that I know of), but from my previous 
experience with FPDF I would probably have started with doing the PDF from

Subject: [web2py] Re: Saving a view as an file/image

Hey John, I dont know if this will help you but there was a time when i needed 
to convert a view to PDF & I used 2 l js libraries, html2canvas & jsPDF, they 
enabled me to achieve my goal that time, you can find the jsPDF package here: 
https://github.com/MrRio/jsPDF   

and the html2canvas package here: 
https://github.com/niklasvh/html2canvas/releases

After extracting all the files from the compressed folders look for these 2 js 
files in jsPDF;  jspdf.debug.js, jspdf.min.js, and the html2canvas.js in the 
html2pdf folder, upload them into your application's static/js directory, from 
there call them in your application's layout page like this:

In the view that you want to convert to PDF have this javascript code:

function genPDF()
{
let pdfName = "licencia";
var doc = new jsPDF({
format: "a4"
});

  html2canvas(document.getElementById("invoicing"), {
scale: "5"
  }).then(canvas => {
console.log("Capturando");
this.imgFile = canvas;
doc.addImage(this.imgFile, "JPEG", 5, 5, 200, 250);
doc.save('filename.pdf');
  });
}

In the same view have a link that when clicked calls the above js function like 
this:

Click to Download as PDF

This should convert you view into PDF or Image as per the usage of both 
liraries.

I hope the maintainers of the jsPDF & html2pdf libraries have not made 
adjustmets that may cause this not to work;

Regards

Hi All,

I have hit a bit of a stumbling block and would like to know if anyone else has 
come across this and how to resolve it.

Situation is as follows:-

I am generating tickets/coupons for users once they have entered all the 
appropriate info which I am doing via normal controller/view using html for 
styling. Coupon consists of 2 images plus some text (nothing really fancy at 
all).

Everything looks okay and as it should in the view with all the correct 
information etc.

I now what to email the coupon to the user. This is where I am a bit stumped.

I am assuming that I will need to save the rendered view as an image/file/.pdf 
if I want the styling, logos, qrcodes etc to be in the email that I will send 
as well as for all the formatting to be as per the view.

Is there any easy way or any way at all to do this?

In the controller I can use the response.render(view, args) but still cant see 
how to create a pdf file from the actual view before sending the email.

Hopefilly I ma missing something simple  

Thanks in advance

RE: [web2py] Re: Saving a view as an file/image

2020-01-28 Thread John Bannister

I have no issue styling the vouchers in HTML  (this is already done in a view) 
my issue  is how to capture that view and send it via email either as message 
or attachment.

Generating PDFs can be a challenge, so it would be much easier to style the 
vouchers in HTML.

Re: QRcodes.  You can even generate QRcodes using Markmin, or, just use the 
Google Charts API directly. Search web for other solutions.
