I am using wtf forms with flask to create a form.
I have a file input, which is styled so the default button is not shown.
How can I dynamically change the style after a file is loaded?
Here is my code:
html:
<div class="file-upload my-form">
<img src="https://i.stack.imgur.com/dy62M.png" />
{{ wtf.form_field(form.file)}}
</div>
css:
.my-form input {
margin: 0;
padding: 0;
height: 100%;
opacity: 0;
}
.file-upload {
margin: 40px auto;
border: 1px solid #149174;
border-radius: 100px;
overflow: hidden;
position: relative;
}
.file-upload input {
position: absolute;
width: 300px;
height: 600px;
left: 10px;
top: 20px;
}
.file-upload img {
height: 170px;
width: 170px;
margin: 60px;
}
how can I change the style on input? or show a label with the file name in the worst case...
In the end I dealt with it like this:
function fileCheck() {
var checked = document.getElementById('file')
if (checked.value.length > 0) {
var file_name = checked.value.split(/(\\|\/)/g).pop();
var re = /(?:\.([^.]+))?$/;
var ext = re.exec(file_name)[1];
if (ext != 'pdf') {
document.getElementById('file-container').style.backgroundColor = '#ca2c2c';
document.getElementById("file-desc").innerHTML = "File Loaded with illegal extension: " + ext + " !!";
document.getElementById("final-submit").disabled = true;
}
else {
document.getElementById('file-container').style.backgroundColor = '#149174';
document.getElementById("file-desc").innerHTML = "File Loaded: " + checked.value.split(/(\\|\/)/g).pop();
document.getElementById("final-submit").disabled = false;
}
}
else {
document.getElementById("final-submit").disabled = true;
}
}
And my html looks like this:
<div class="file-upload my-form" id="file-container">
<img src="static/images/upload_icon.png" />
{{ form.file(oninput="fileCheck()") }}
</div>
I have a Django application and I'm using pythonOCC package in it. I have to display the 3D .stl, .stp, .igs files in my template. Normally, when I call the render() function, the following outputs appear on my vscode console and since flask app created by pythonocc instead of django starts running in localhost, my index.html is never rendered. However I need to display the files in a Django template. That's why I have extended the X3DomRenderer Class such as below.
My custom X3DomRenderer class:
class CustomX3DomRenderer(x3dom_renderer.X3DomRenderer):
def render_to_string(self):
self.generate_html_file(self._axes_plane, self._axes_plane_zoom_factor)
return open(self._html_filename, 'r').read()
the HTML codes that returned from render_to_string() function:

and I have added these HTML codes that I got from render_to_string() function to my template file. The viewer's grid has shown but the 3D object hasn't because of the error below.
Page not found: http://127.0.0.1:8000/file/occview/shp6b8ef6d6e61744489de16a6798cfe998.x3d
The library creates that .x3d file in the same directory with the file that I wanna render to template but I guess the viewer is looking for this .x3d file in the error which I mentioned before even I sent the directory. I couldn't find the cause of this error. Am I missing something?
Thank you!!
I know there is much of code below, but i had to show the html/css/js and flask+mysql codes for better understanding. Ask if anything is not clear.
The problem is that, after i give the credentials in the register page and i submit, i expect for it to add the values to database and to route to the login page, but what it does actually, is that it reloads the same page, and the link look like this,
i.e.:
"http://127.0.0.1:5000/register/patient?name_surname=jack+stathem&email=jsm%40outlook.com&ssn=123456789&age=40"
i am having some semantic error and i cant figure out how to fix.
Thank you

self.end_headers()
query_components = parse_qs(urlparse(self.path).query)
if 'mymessage' in query_components:
MyMessage = query_components["mymessage"][0]
send_message = f'INSERT INTO lora_messages (mymessages, yourmessages) VALUES ("{MyMessage}", "")'
insertmsg.execute(send_message)

while mymsg is not None:
mymsg = mymess.fetchone()
mymessagetemplate = f"<div class='chat'><div class='mine messages'><div class='message'>{mymsg}</div></div>"
How can I get this program to write each line one by one? The result I get is that {yourmessagetemplate} only shows the last message in the DB which is "None" for both sides of the conversation and omits the rest of the messages.
The code is overwriting the message templates in each iteration of the while loops. You probably want to collect each template in a list, and then join them together once they have all been collected.
# Create a list to hold templates
yourmessagetemplates = []
yourmess.execute("SELECT yourmessages FROM lora_messages WHERE yourmessages != ''")
yourmsg = yourmess.fetchone()
while yourmsg is not None:
yourmsg = yourmess.fetchone()
yourmessagetemplates.append(f"<div class='chat'><div class='yours messages'><div class='message'>{yourmsg}</div></div>")
# Join the individual templates into a single piece of html.
yourmessagetemplate = '<br>'.join(yourmessagetemplates)
# Create a list to hold templates
mymessagetemplates = []
mymess.execute("SELECT mymessages FROM lora_messages WHERE mymessages != ''")
mymsg = mymess.fetchone()
while mymsg is not None:
mymsg = mymess.fetchone()
mymessagetemplates.append(f"<div class='chat'><div class='mine messages'><div class='message'>{mymsg}</div></div>")
# Join the individual templates into a single piece of html.
mymessagetemplate = '<br>'.join(mymessagetemplates)
I'm building a pyqt5 desktop interface where I'm using QWebEngineView to show a html file where I show a Leaflet map. This is working fine.
The next step is to export all features the user added to the map. When I click on "Export Features" on the map nothing happen, but when I open the same html file on my Chromium web browser, the "Export feature" opens the download dialog fine.
PyQt5 script:
self.MainWindow.webMapViewer = QtWebEngineWidgets.QWebEngineView()
self.MainWindow.webPageLayout.addWidget(self.MainWindow.webMapViewer)
self.html_path = os.path.split(os.path.abspath(__file__))[0] + r'/html/test.html'

That popup window is generated by the browser, in the case of QWebEngine we must create it. To start, the signal indicating the download must be detected, and this signal is downloadRequested from the QWebEngineProfile. That signal sends us a QWebEngineDownloadItem object that handles the download, in it we create a dialog window with the help of QFileDialog. For this case we will create a custom QWebEnginePage as shown below:
