I want to implement enhanced blowfish algorithm(or any other algo) for encryption in cloud computing on salesforce platform .
For this i want to create a VF page which has algo code written in apex .
through this page i want save the details (say merchandise object in warehouse app) of object in encrypted form on detailed page .
it means i enter plain text on vf page and it shows cipher text on detailed page.
and in return vf page should display this saved data in decrypted form(plain text).
Is this possible in salesforce and if yes, what extra api or plugins I need.
Not sure exactly what you are looking for but this may be of help :
Try System.Crypto class :

hi I am working on the fillable pdf in Salesforce, i have uploaded the pdf in the static resource in Salesforce , now need to handle the data to fill in it and download the file , can any suggestions to achieve it
Thanks in advance
There is no functionality in Apex to interact with fillable PDFs. While it's possible to interact with binary formats such as PDF in Apex, it's difficult, slow, and subject to the extensive limitations of the Salesforce governor limits. You'd have to implement this from scratch based on your knowledge of the PDF format.
You will likely have much more success either building PDF manipulation functionality in JavaScript on the front end, or calling out to an external service on Heroku or elsewhere that uses PDF libraries available in some other stack to do this work.
Salesforce does not support inputs on generated pdf via Visualforce
pages.
To achieve this functionality, you can create a form with all the
inputs that are required in the pdf.
Once the user fills in the information in the created form and submits it, generate the pdf with the filled information by the user.
Bonus: you can save the filled-in information as well by creating a record under the object for future reference (data is everything)
I want to develop a blog application with Django backend and React frontend. I shall be using Postgresql.
I want to use a rich text editor like Quill to write the blog article. My questions:
I heard that article written in a text editor needs to be converted to HTML before saving in the database. If so, how do I do this in Django Rest Framework?
How do I present the article keeping the same style and formatting in the frontend from the database?
Say, I include multiple photos in the article. How do I save all the photos in the database? i.e. what should be the schema then?
I want to have my doubts clear before I jump in.
I'm also doing the same thing at the moment. For your answers :
In DRF, the simplest way to post the data is by using Textfield in your model. Rich text field (with Tags) will be stored in the Postgres. In the Admin page or the DRF API you'll see something like this
Then, to re-render it to the front end, you can use any HTML Parser library. for example I'm using "react-html-parser" that simply convert the rich text into the defined styling.
As for Image, this is a bit tricky, and I havent done this part myself but what i could think of right now is you would create another model & end points to store the images.
when sending the post request to the django, you would convert the base file path/url from the front end to back end. example :
original > http://localhost:3000/image/efewf23r.jpg
new (django) > http://localhost:8000/media/img/img_model/efewf23r.jpg
then do a second post request to the image itself and make sure django would rename the the file as per what we set above.
Let me know if you found a better solution.
It's been long since I posted this question. After that, I have gained enough working knowledge to make Quill.js (the rich text editor I'm using) work with React.JS, or, in my case Next.JS. So, this is focused on Quill.js only. The Quill npm package more specific to ReactJS is react-quill. I am presenting it as beginner friendly as possible.
A built-in function is provided with Quill: editor.getHTML(). editor is the current editor instance, where one types the content. This method generates the innerHtml of the content one prepares in the editor.
To save it to the databse, simply POST it to your back-end. But you must sanitize this innerHtml before passing it to the database. Can't say about server-side but I had to do this sanitization on the client-side. One good package is DOMPurify. You need to save this to the database if you want to present it in the same manner as it was typed in the browser.
The first point also provides the solution to my 2nd question. But one important point: The content one writes in Quill editor is also available as a JSON like format called quill-delta. You can get the delta with the function editor.getContents(). You need to POST it to the database if you want to edit the content in a later time.
To edit, you need to get this delta from the database and then initialize Quill editor with this delta in the value attribute.
For example, the text in orange is the delta representation of the text in the editor:
codepen source.
There is another function editor.getText() which extracts all the text from the editor.
Photos. Generally in Quill, you simply put the photo in the editor and Quill generates a base64 encoded delta for the photo. It's this easy. You don't need to worry about separate image fields.
I'm looking for a way to create a search box in wordpress, where visitors can search a number from the database. Is this possible? I have several package numbers in my database. I want to give my visitors the ability to search for their package number and request the information that comes with the number.
What you want to do can be done.
I suggest a different approach than using wp-exec. (I just looked at wp-exec website, and that plugin was created for WordPress 1.5, which means it hasn't been updated in about 5 years).
The content you want to display exists entirely outside of WordPress. I suggest you use a custom page template - see
http://codex.wordpress.org/Pages#Creating_Your_Own_Page_Templates
In this case you would not use WordPress posts or pages or custom post types. On the custom page template you would write (or have written if you don't have the knowhow to do it yourself) PHP code to extract the info from the database and display it on a page.
For pages like that you would be using WordPress only as a container within which to display the results - they custom page would appear in the site Nav, The page of results would use the site's theme to display so it looks like the rest of the site.
But the code to display from the database would not use the WordPress loop. It would be PHP / MySQL data retrieval and display code.
I really doubt you will find a plugin that lets you display results from an external database, formatted the way you want them to appear. The reason is every external database is different, has different tables and table structures. And no two sites will want the external data visually displayed in the same way. So there is little generalization to encapsulate in a plugin as everyone wants it different.
I've created pages on some sites along the lines of what you want to do thus I know it can be done. But it requires writing custom code.
I'm creating a social network, and in the user info section I've made it possible for the user to add there Facebook link into the database table via a input form.
Now when they add this link, it sends it to the database and then it returns and echo's out the submitted data into both the user info page and the user status stream, this enables others can see there newly updated info.
Only problem is, the link submitted is not active when it returns from the database, is there anyway either in my page, or within the database, I can tell this to be an active link, maybe even some JavaScript that detects inactive links?
Any help would be greatly appreciated.
Thanks,
What do you mean by "make the link active"?
What language are you developing in?
To use a database field to generate a clickable link in a web browser, you create the HTML framework and then insert the database output into the relevant position.
In PHP, for instance:
<?php echo $linkURL; ?>
Would create a clickable link which would direct visitors to the URL in the $linkURL variable.
I am looking for some initial direction on this one because I cannot seem to find my way with it. Let me explain...
I am developing a website wherein a logged in site member (Joomla 1.6) can fill out a simple form and attach a pdf to be uploaded upon submission. The user then clicks the submit button and the page will refresh to a new and unique web page.
User Submits data on http://www.examplesite.com and then after submission a new web page is generated that is called http://www.examplesite.com/userSubmittedValue
This newly generated web page would come from a template that is specified by the administrator and, most important, it will display all of the information that the user submitted. Also, there would be a link to download the pdf they uploaded. The user could then view a list of all the pages they have created in this manner via their profile.
I have seen this all over, but I am at a loss for how to generate this. Any help is much appreciated.
This is not something you will be able to easily do or get a detailed answer for here. If you just wanted to do the submission form with a thank you page that shows the data submitted you could use any number of form wizard type extensions - http://extensions.joomla.org/extensions/contacts-and-feedback/forms
If you just needed a way for users to upload PDfs and have access to them you could use one of the file management extensions that offer front end upload features - http://extensions.joomla.org/extensions/directory-a-documentation/downloads
If the additional data that is being submitted is simply data related to the file - title, description, etc then one of the file download components should work fine for you. The choices are limited in 1.6 at this time though so you might have to go with 1.5 to get the extension that works best for your needs.
So this probably isn't the best way to do it if your using Joomla but it just might help.
I would use PHP and inside of you're directory have a file like "template.html". Then I would create some php to handle the task of....
Opening "template.html"
Finding and replacing the values that the user passed you
Save the "template.html" under a new name (userSubmittedValue.html)
Again, I never really use Joomla. If you were to try this I'd suggest checking out php's file system functions (http://us2.php.net/manual/en/ref.filesystem.php).
Hope this helps a bit.
