I'm having a Django stack process issue and am wondering if there's a way to request user input.
To start with, the user is loading Sample data (Oxygen, CHL, Nutrients, etc.) which typically comes from an excel file. The user clicks on a button indicating what type of sample is being loaded on the webpage and gets a dialog to choose the file to load. The webpage passes the file to python via VueJS/Django where python passes the file down to the appropriate parser to read that specific sample type. The file is processed and sample data is written to a database.
Issues (I.E sample ID is outside an expected range of IDs because it was keyed in wrong when the sample was taken) get passed back to the webpage as well as written to the database to tell the user when something happened:
(E.g "No Bottle exists for sample with ID 495619, expected range is 495169 - 495176" or "356 is an unreasonable salinity, check data for sample 495169"). Maybe there's fifty samples without bottle IDs because the required bottle file wasn't loaded before the sample data. Generally you have one big 10L bottle with water in it, the ocean depth (pressure) and bottle ID where the bottle was closed is in a bottle file, and samples are placed into different vials with that bottle's unique id and the vials are run thought different machines and tests to produce the sample files.
My issue occurs when the user picks a file that contains data that has already been loaded. If the filename matches the existing file data was loaded from I clear data associated with that file and reload the database with the new data, sometimes data is spread over several files that were already loaded and uploader will merge all the files, including some that weren't uploaded, together.
A protocol for uploading data is for the uploader to append/prepend their initials onto a copy of a file if corrections were made and not to modify the original file; a chain of custody. Sometimes a file can be modified by multiple people and each person will create a copy and append/prepend their initials so people will know who all touched the data. (I don't make the rules I just work with what I have)
So we get all the way back to the parser and it's discovered the data already exists (for a given sample ID), but the filename is different. At this point I want to ask the user, do you want to reload all the data loaded from the other file, update existing data with the new file or ignore existing data and only append new data.
Is there a way for Django to make a request to the webpage to ask the user how it should handle this data without having to terminate the current request? - which the webpage is waiting for a response from the server to say the data was loaded and what errors with the data might have been found -
My current thoughts are to:
Ask the user before every file upload how a collision should be handled, if it happens
Or
Abort the data load, pass an error with a code back to the webpage, the error code indicates to the webpage that the user has to decide what to do. Upon the user answering, the load process is restarted with the same file, but with a flag to tell the parser what to do when the issue is eventually encountered again.
Nothing is written to the database until a whole file is read so no problem aborting the process and restarting if the parser doesn't know what to do, but I feel like there might be a better way.
I'm new to python and doing a work project that involves juggling a lot (5-10k) of "places" (polygons representing regions) in google earth. As such, I wanted to run a list compare between the places I have in google earth against a txt file list of places I should have. The only problem is that I cannot seem to find a way to copy paste or otherwise capture the name text of the google earth places. Copying with control c or right click copy copies them as a KMZ file, or when pasted into a text editor gives the full source from their "properties" tab. I'm fairly confident in manipulating and comparing the lists once I have the data in that format, but could really use some help in attaining it as such.
First right-click on saved places in Google Earth and save as KML (text) file.
Next, you can use Python to extract the place names from the KML file.
Here's some sample code using pykml module to parse out the place names.
from pykml import parser
with open('places.kml') as f:
root = parser.parse(f).getroot()
# iterate over each placemark
for pm in root.Document.Placemark:
name = pm.name.text
print(name)
currently I'm working over a task, which require every Django user to have different locale file and translation of course e.g. different translation for the same app.
I'm tried to do some changes on my own scenario and the next lines are finished and works fine but I also met some troubles
whole app is translated on english and german
when I create new user, I copy default translation file .po to new directory related to this user. For this case I made container app which hold all custom translation and directory with schema like this 'apps/trans/locale/user1/', 'apps/trans/locale/user2/' and so on.
these paths are added into settings.LOCALE_PATHS when app is started.
I have implemented rosetta into my Django admin and display correct .po file for all of them (custom .po)
The Django tempalatetags i18n.py was copied into my teplatetags directory and was extended for my purpose
I also want to do some custom modification into django.core.translation module and I also copy this file into my project, but now I do not know how to load this module correctly to override the default Django functionality, because I want to replace the default translation with custom here
for now I use _ _ import _ _ and then I just replace sys.modules['django.utils.translation'] with my module. is this a correct way?
So anyone with idea?
Thanks
One of the fields in my database table is named DATEOFDISCHARGEFROMITU. In any report output, this displays as DATEOFDISCHARGEFRU. I've figured out that the missing characters form the word 'OMIT', which makes me think it's related to this old problem in a previous version of ApEx (I'm using version 4.1.)
Is there a way to display the whole field name in the report header when the field name contains the string 'OMIT'?
Note: Using html character codes will allow the field name to display properly, but then when the report is exported to CSV the character codes are of course shown instead of the full field name. I need a solution that works for exports as well as displaying onscreen.
Platforms (tested): Oracle Application Express (APEX), Version 4.0.2
Note: I am not sure how the linked OTN post is relevant to your problem aside from the coincidence that their file export contains the word "OMIT" and your column title contains the word "OMIT".
It's safe to say that "OMIT" isn't an APEX or ORACLE reserved word that is sabotaging your output. However, if you were talking about a scrap of SQL that attempted to create a table named "SELECT" or "WHERE"
i.e., SELECT * FROM "SELECT" WHERE...
you'll be blocked by the RDBMS from proceeding. :)
I tried an export with a query that contained a column header labeled "OMIT" (see the far right in the example.) The .csv file interpreted by Microsoft Excel looked like this:
I wrote up a separate Q&A post about creating dynamic APEX report headers to answer your follow-on question about a suitable solution for providing a clean, htmlcode-free output when a report is eventually exported to a text, comma separated (or other delimited) output.
In summary, the linked post suggests to set up a dynamic PL/SQL Function within a page item. The page item can be referenced directly in the report column header definition. This is a screenshot demonstrating a possible solution:
The link to the general explanation has more details on the APEX design tasks that gets to this final product.
Onward.
I solved this by using this solution for exporting to csv without an enclosing quote character - as that was another challenge I was faced with for the particular application I was developing. By manually creating the export file I was also able to define the column headings exactly, and the "OMIT" issue did not occur.
Technically that's not a solution for displaying a report with the required headings that can also be exported (Richard's response does that) but it does what I need it to and solves the immediate problem of the DATEOFDISCHARGEFROMITU column heading.
I have a website (Coldfusion) on which I want to offer multi language, but no idea what is the best way to do this.
There 2 plans I have:
1:
Of course all content (text) is in a database.
If a user would want a different language, the user would click on a link/flag, this would put the requested language in a session variable, for example: session.language = "es"
In the database I would have 2 columns (every language has 1 column) and then select the text which belongs to 'es'
Every page would then do a request to the database to get the text beloging to the session.language.
PROS: Relatively simple to implement
CONS: SEO wise I don't think this could be very good. http:// www.domain.com/page.cfm would give an english text or spanish text (or other language). Google will not add duplicate URL's
2:
Do something with http:// www.domain.com/en/page.cfm for english and http:// www.domain.com/es/page.cfm for english.
With a URL rewrite rule the language value in the URL http:// www.domain.com/en/page.cfm would actually be a page http:// www.domain.com/page.cfm?language=en
The url.language variable will then select the correct language from the database.
PROS: Unique URL for each language. Good for SEO and Google indexing.
CONS: A bit more difficult to implement. (I think)
Or does anyone have other / better ideas?
Thanks!!
You should always first check the browser header "Accept-Language" for the default language(s) (the correct standard way to do it), and offer links (the intuitively seemingly right way) only as an alternative.
Doing it in a database doesn't seem very standard. Let's assume you would like to use MVC architecture (model-view-controller). Most software uses keys in the presentation layer (view) (eg. html) and along with the presentation layer, you have language files (in Java, this is typically properties files) which are mapped simply by their filenames, and can be modified by regular users, without any special skills, such as professional translators with no computer skills. Certainly you could put it in a database, but then it is just more work, and moves the information out of the presentation layer.
There are various libraries for doing this. You should find the normal one for your application. Please edit your question to include what you are using to develop the application. (eg. JSP, Tapestry, Wicket, ASP, PHP, etc.) So for example, if you wanted to use JSPs, I would then suggest you use the JSTL tag library's language support. Or if you were using Tapestry, I would point you to http://tapestry.apache.org/localization.html or http://tapestry.apache.org/tapestry4.1/UsersGuide/localization.html
To look it up, you can look for the terms "internationalization" aka "i18n", or "localization". (The terms don't mean the same thing, but few use them correctly, so either works. http://www.w3.org/International/questions/qa-i18n)
I would go for option 2. Every translation should have its own url. Links to your website will already be in the intended translation.
To store translations in a database, I wouldn't put every translation in a seperate column, but rather put them in a seperate table:
Table Posts:
- id
- title_id
- ...
Table Translations:
- label_id
- value
- country_code
- language_code
Where title_id matches label_id
This way you won't have to alter your table structure when a new translation is added. This allows you to have infinite translations for any label or text.
To effectively do a multi-lingual site then you need set a rule for yourself that NO TEXT is ever put in the source as hard coded. It either needs to come from the database and / or a Resource Bundle.
Text from the database
You need to make sure that the column you are storing your data in is unicode otherwise you'll have issues with accented character. Also don't have a column per language as this is not scalable, do what #jan suggests and have a translations table where the items are keyed on a reference as well as a language.
Resource bundles
You are not going to want to get every last little bit of text from the database so for those you can utilise a resource bundle. This is an, admittedly old, link http://www.sustainablegis.com/blog/cfg11n/index.cfm?mode=entry&entry=FD48909C-50FC-543B-1FE177C1B97E8CC1 from Paul Hastings's blog about some solutions to resource bundles. To be honest his blog is an excellent resource on this very subject.
With regards to how you handle the URLs do not do option 1 as you quite rightly identified you will cause issues the SEO rankings of the page and it will mean that users cannot correctly share or return to the page.
Two approaches are having the language code in the URL as you identified in option 1.
Pros
Simpler to configure
Cons
You have one application which means that as you add more languages you add more complexity and weight on the memory of that app
Or you can have a different sub domain or domain per application e.g. es.yourdomain.com or yourdomain.es they can all be the same codebase
Pros
Each language is a standalone application meaning it has it's own memory
Cons
more effort to configure
http://i18n.riaforge.org/ has a download for i18n. It can be used to make sure that all string labels match. That way if some one wants to change "Save" to "Update", it can all be done in one spot.
It is also important to consider the technical background of those that will being doing the translation. It is often easier to get the translation team to edit files in notepad as opposed to updating a db. Text files work well with version control.
The best way i found is to use an XML to hold just that pages language stuff, one xml to cover each page, and you then vary it for language. when the page loads, just load a different XML from the database or files... many ways to do this. all other methods i have tried have their issues, and at least this one allows you to take a language XML, hand it to someone who will copy it, and then change the boxes... you put it in the DB to serve it.
one can also do this for text, and have the DB make the XML for just the text for that page by using a list of items to include in the XML for the page.
once you get the idea, the rest becomes very easy...
and given CF ways of accessing such data with dot notation, easy peasy to us
say you have "Load Images"
in english xml it may be <LoadIMGS>Load Images</LoadIMGS>
in chinese it may be <LoadIMGS>加载图像</LoadIMGS>
or <LoadIMGS>Jiā zǎi túxiàng</LoadIMGS>
regardless, in your CFM code you would just put #variablename.LoadIMGS# in the place... i would also suggest putting in the loadimages tag the size the font should be adjusted to if not normal size. that way, when translations are too large, you can shrink that font there for that... etc.
enjoy!!!
