How to fix scrapy rules when only one rule is foll

This code is not working:

name="souq_com"
allowed_domains=['uae.souq.com']
start_urls=["http://uae.souq.com/ae-en/shop-all-categories/c/"]

rules = (
    #categories
    Rule(SgmlLinkExtractor(restrict_xpaths=('//div[@id="body-column-main"]//div[contains(@class,"fl")]'),unique=True)),
    Rule(SgmlLinkExtractor(restrict_xpaths=('//div[@id="ItemResultList"]/div/div/div/a'),unique=True),callback='parse_item'),
    Rule(SgmlLinkExtractor(allow=(r'.*?page=\d+'),unique=True)),
)

The first rule is getting responses, but the second rule is not working. I'm sure that the second's rule xpath is correct (I've tried it using scrapy shell ) I also tried adding a callback to the first rule and selecting the path of the second rule ('//div[@id="ItemResultList"]/div/div/div/a') and issuing a Request and it's working correctly.

I also tried a workaround, I tried to use a Base spider instead of a Crawl Spider, it only issues the first request and doesn't issue the callback. how should I fix that ?

The order of rules is important. According to scrapy docs for CrawlSpider rules:

If multiple rules match the same link, the first one will be used, according to the order they’re defined in this attribute.

If I follow the first link in http://uae.souq.com/ae-en/shop-all-categories/c/, i.e. http://uae.souq.com/ae-en/antique/l/, the items you want to follow are within this structure

<div id="body-column-main">
    <div id="box-ads-souq-1340" class="box-container ">...
    <div id="box-results" class="box-container box-container-none ">
        <div class="box box-style-none box-padding-none">
            <div class="bord_b_dash overhidden hidden-phone">
            <div class="item-all-controls-wrapper">
            <div id="ItemResultList">
                <div class="single-item-browse fl width-175 height-310 position-relative">
                <div class="single-item-browse fl width-175 height-310 position-relative">
                ...

So, the links you target with the 2nd Rule are in <div> that have "fl" in their class, so they also match the first rule, which looks for all links in '//div[@id="body-column-main"]//div[contains(@class,"fl")]', and therefore will NOT be parsed with parse_item

Simple solution: Try putting your 2nd rule before the "categories" Rule (unique=True by default for SgmlLinkExtractor)

name="souq_com"
allowed_domains=['uae.souq.com']
start_urls=["http://uae.souq.com/ae-en/shop-all-categories/c/"]

rules = (
    Rule(SgmlLinkExtractor(restrict_xpaths=('//div[@id="ItemResultList"]/div/div/div')), callback='parse_item'),

    #categories
    Rule(SgmlLinkExtractor(restrict_xpaths=('//div[@id="body-column-main"]//div[contains(@class,"fl")]'))),

    Rule(SgmlLinkExtractor(allow=(r'.*?page=\d+'))),
)

Another option is to change your first rule for category pages to a more restrictive XPath, that does not exist in the individual category pages, such as '//div[@id="body-column-main"]//div[contains(@class,"fl")]//ul[@class="refinementBrowser-mainList"]'

You could also define a regex for the category pages and use accept parameter in you Rules.
