            You get the KeyError: 'date' because it is not being passed in the function when you use apply() after the groupby. You try for example adding a lambda to the apply. I'm not sure about the intended behavior, but it gets the function working. Change it to this:

            Reindexer configuration - Will it reindex new data for existing Indexes
            Asked 2019-Dec-04 at 14:42

            MarkLogic - 9.0.8.2

            We have around 5 indexes created which are used to search data (19M records) within MarkLogic

            Now we want to add one more index, resource utilization will be depend on value defined in reindexer throttle (Large numbers mean work more harder reindexing)

            As reindexing will take few hours/days to finish it up in production environment and should not have impact to performance on production environment, we followed (reindexer enable false during business hours) best practices suggested by MarkLogic.

            Now my question is, with Reindexing disabled, will adding new data will be indexed for existing indexes which were created initially?

            ANSWER

            Answered 2019-Dec-04 at 14:42

            The reindexer setting applies only to the updating of existing data following configuration changes. With or without reindexing enabled, newly inserted data will be indexed with the configuration that is active during the insert.

            In many cases this means that index changes should be applied in multiple steps: first, adding any new indexes required by the application, then deploying code with dependencies to those indexes after reindexing is complete, and finally removing any indexes made obsolete by the deployed code.

            I don't think this problem is occurring specifically because you're trying to scan multiple sheets in a document. I think the problem is with the data itself, and the error could have just as easily occurred in your single data set.

            Looking at your Excel file, I think the problem is that both sheets have two rows with the datetime 8/27/2019 10:30:00 PM. I think df.set_index('dtime').asfreq('-30T') only works if the dtime column contains no duplicates. Try removing duplicates beforehand, either by manually editing the data or by dropping duplicates from the dataframe.

            I'm trying to use std::map with a custom class and in the course of the process the program has to call std::map::find in order to resolve a key to a pair. The custom class doesn't seem to fit well in terms of comparisons.

            You have to define a strict order to use class index_t as key in a std::map.

            It doesn't need to make sense to you – it just has to provide a unique result of less-than for any pairs of index_t instances (and to grant a < b && b < c => a < c).

            Magento 2 Category SEO friendly URLS
            Asked 2018-Dec-18 at 09:45

            I have a Magento 2 website and require some direction with setting up sub-category urls to be SEO friendly. The Navigation menu work just fine i.e

            Grooming Kit

            www.mywebsite.com/product-grooming-kit.html the issue i'm having is with sub-categories in the left sidebar filters which when a specific category is clicked on it displays as following url with a number id

            www.mywebsite.com/product-grooming-kit.html?grooming-kit=32

            I want it to look like

            www.mywebsite.com/product-grooming-kit/grooming-kit-mens/

            I have added this to custom urls manually, cleared cache and still no changes?

            In Magento 1.9 i would do a reindexer using ssh and would update urls. Not sure how to do this in Magento 2 without installing a third party extension.

            Any help would be much appreciated.

            please look at:

            system->config->catalog->seo->use category paths in product url->yes

            and then also important: system->config->catalog->seo->canonical for categories/products->yes

            For the URL Rewrites, you should use an extension. I recommend OlegKoval_RegenerateUrlRewrites but only if you are using a version up to Magento 2.2.4. Then you should use OlegKoval_RegenerateUrlRewrites Version 1.3.0.

            Please look also at a SEO extension that resolves the duplicate content issue if you are using multiple store views for different languages. (Maybe this one).
