Tricky problem with built-in recipe - need your help.... :(

stachuman · 05-04-2011, 11:50 AM

Dears,

There is a built-in recipe - 'Rzeczpospolita OnLine' - in short words - on linux this recipe does not work, on on PC under windows it works, on other - not..

So, I do not know python, anyway - did try to investigate ( running calibre in debug, also - same - under linux ) and my guess is as follow - there is something wrong with rss links ( not being 'translated' ?? )

The recipe changes the link slightly adding 'print=tak' - to get the printable version -
taking the link (as example )

http://rss.feedsportal.com/c/32536/f...ml/story01.htm

If I'd put that into web viewer - it is immediatelly translated ( java code I guess ) into: http://www.rp.pl/artykul/549282,635828.html

Function in recipe would convert it into: http://www.rp.pl/artykul/635828.html?print=tak

What is absolutely correct - and get what it should - unfortunately what I see in the log is:

http://rss.feedsportal.com/c/32536/f....htm?print=tak

So - the original rss link is not 'converted' into desired one.

I don't understand why on one PC - even this - not-so-correct - link is working fine ( under windows ), while on the other PC - this is not working.

To be sure - I use same recipe - I did copy from working PC the recipe code and used it under linux as a custom one.

Any help.... please...

Thanks,
Stan

You need to implement the get_article_url method in your recipe to get the correct URL from the RSS feed.

Hello,

Thanks for suggestion but... hm, not sure - it will help me yet - I did investigate further and what I found is - from RSS the link guide to a web page which contain only advert and link to the real article.

Unfortunately this page is shown not always - sometime yes, sometime no (not sure of condition) - the link on this page seems to have constant label ( something like - 'click to get the article' ... )

So, in recipe I'd need to set a condition - and eventually follow the link to be at the proper page - I guess - I'll need to override the method you gave me - right? Comparing the input url - if it points to url with advert - find on the page the proper link and return it - sounds good?

Yes, that is what you need to do.
