I am using render in Django to load an HTML file that contains different calculators/simulators. I would like to use render because I believe it may help obfuscate the HTML to code to prevent people from doing right click view source? Is this accurate? Are there other ways to achieve my goal of not having my HTML code be viewable?

Currently I am Working on a workflow where on the left side are input fields and on the right half is a scalable pdf.
But actually I am not able to show a PDF in an iframe.
I am using django 2.1.1(python 3.7.2) on windows.
Is there any solution to display a pdf in an iframe?
I hope you have some ideas..i looked up many sides an tried different solution but actually the pdf document is not shown..
Hope to hear from you soon!
Kind regards
I have experienced a similar setting where I wanted to render a PDF in a webpage.
For that, I did the following :
Wrote a view method (in views.py) that renders the pdf's name. Indicated in the urls.py the path used for the view method. Next, in the HTML file, I use the following line of code :
<iframe id="iframe_pdf" src="{{ doc_file.url }}"
style="width:800px; height:800px;" frameborder="0"></iframe>
The {{ doc_file.url }} is the data obtained from the View method, it returns the PDF file location as a string. In my case, the pdfs were stored in the MEDIA_ROOT directory set in settings.py.
I'm using pdfkit to generate a PDF of a Django template (doing this by getting an HTML string of the page from Django's get_template and render functions and passing that string to pdfkit... see post).
On this page, I have some TextArea's that can contain many lines of text, and by default, they just get cut off when generating the PDF.
I've tried to fix this by using some javascript libraries (I've tried several) to automatically expand the TextAreas on page load. I can get these to work perfectly on normal pages, but when I try to include it on the PDF template, I get various errors ranging from not working at all to expanding the TextArea way too much. My first assumption was that there was some styling differences that were causing the issues, but I'm fairly certain I've ruled that out. I tried to load the PDF template directly as a view, and the TextArea's resized correctly, leading me to believe that there's something with pdfkits generation that isn't playing nicely with the resizing.
Given this, I tried to look if pdfkit has any suggestions for issues like this and couldn't find any, and I also tried to use different input types other than TextAreas, none of which were able to display newlines correctly.
I can't think of any other potential solutions at this point, and I'm open to suggestions. Please let me know if you feel I should provide additional information, and thank you in advance.
I ended up finding a relatively simple fix. Because I was using django forms, I was pretty easily able to change from displaying the form Textarea:
{{ form.paragraph_data }}
to displaying just the plain text:
{{ form.paragraph_data.initial }}
However, this initially caused the newlines to not display correctly, because HTML doesn't process them in a plain string. So I added some processing in the creation of the form to replace the newlines with <br />s:
form.fields['paragraph_data'].initial = form.fields['paragraph_data'].initial.replace('\n', '<br />')
Finally, I had to add the safe filter to Django templating line to tell it to actually render the HTML rather than cleansing it:
{{ form.paragraph_data.initial|safe }}
Again, this was partially easy because of Django forms, but it should translate relatively easily to a more standard javascript/html solution.
I want to move some parts of a main template into partials which shall not need django rendering (i.e. pure html/js) and use them in a ng-view in the main template.
However, the partials have Django formsets (using crispy) in them i.e useless without Django rendering.
Moreover, I do not want to write the complete formset HTML by hand.
How can I do this?
Maybe you have a less or sass file too. This file, like your form, it's unusable without preprocessing.
Review code from https://www.djangopackages.com/grids/g/asset-managers/ for inspiration and look at https://docs.djangoproject.com/en/dev/howto/static-files/ to learn how to do it.
Hard part is not do it because its easy make a static finder. Hard part is do it in development staging in a transparent way.
You can request your partials from the server and put them into the $templateCache yourself using the filename as a key.
This way, when a partial .hmtl file is request, it will get the django rendered HTML.
$http.get('myForm.html', {cache:$templateCache});
You'll want to eagerly load these partial templates, as if the partial template is not in the cache, then it'll request the static html.
Hope this helps
I have a view called "contests_slider" with a block display. I'm hiding all fields and using a "Customfield: PHP code" field instead which calls a function called display_front_contests(). In that function, querying the database and building some html and returning it. I'm displaying the output in a block. The problem is Drupal is adding alot of extra divs that I don't want. I went to "Theme: Information" and copied the theme "views-view-field.tpl.php" to "views-view-field--contests-slider--block-1--phpcode.tpl.php" and put just: in it and it's still outputting all the extra html.
Any ideas? am I using the wrong template?
If you are only using views to create a block, but otherwise query the datebase, create the markup etc, you should consider making a block in a custom module. All the work is in the code you have already written. That way you wont have to think about the many templates that views uses, but instead you'll just use the block.tpl.php.
Take a look at hook_block for info on how to do it.
Hey everyone, I would appreciate a pointing in the right direction with the problem I'm having. In short, I'm working on an application that will create PDFs using TinyMCE and ColdFusion 8. I have the ability to create a PDF by just entering in text, pictures, etc. However, I want to be able to import an html template and insert it into the TinyMCE .
Basically, I have a file directory code snippet that lets me browse through my 'HTMLTemplates' folder, and am able to select an HTML document. Now, I want to be able to take all the code from that selected HTML document and insert it into my TinyMCE box. Any tips on how I might do this, maybe?
Thanks!
If I understood you correctly, you already have a TinyMCE plugin which pops up a window and allows you to browse the certain directory using existing cfm page which you render within the popup window. Right?
If not, you should start with this. Not sure how easy it is done in current version, but in the older TinyMCE I've created the custom upload plugin (needed to track the site security permissions for current user) pretty quickly.
Next, I can see two quick ways to pass the server file contents to the client-side:
Make it available via HTTP so you can make the GET request and read contents into the variable.
Output it on the page using CF (say, on form submit when file selected) and grab using JavaScript.
I'd personally tried the second option. After you grab the text into the variable you can put it into the TinyMCE using it's API.
It can be as simple as output escaped text into the hidden div with known ID and read it using DOM operations (assuming that there is cfoutput around):
<div id="myTemplate">#HTMLEditFormat(myFileContents)#</div>
Also you can output the text directly into the JavaScript variable (of cource, with accurate escaping), maybe like this.
<script type="text/javascript">
var text = '#HTMLEditFormat(myFileContents)#';
</script>
Most advanced and possibly better for performance (and definitely "cooler") way is to use the concept of script tags as data containers, like this:
<script type="text/plain">
#HTMLEditFormat(myFileContents)#
</script>
Last time I've seen this in Nadel's blog, I think. Read it, pretty interesting.
Hope this helps.
