Usage Example not working - Fundamentals

Hi.

I have tried this example code from the Data Reference:

from quantopian.pipeline import Pipeline  
from quantopian.pipeline.data.morningstar import Fundamentals  
from quantopian.pipeline.domains import US_EQUITIES  
from quantopian.research import run_pipeline

# Construct a factor that simply gets the most recent total revenue value.  
total_revenue = Fundamentals.total_revenue.latest

# Add the factor to the pipeline.  
pipe = Pipeline(  
        column={  
                'total_revenue': total_revenue,  
        },  
        domain=US_EQUITIES,  
)

# Run the pipeline over a year and print the result.  
df = run_pipeline(pipe, '2015-05-05', '2016-05-05')  
print(df.head())  

And it doesn't work at all. How can I solve this?

Regards,

Thank you for pointing this out. The correct code should be


from quantopian.pipeline import Pipeline  
from quantopian.pipeline.data.morningstar import Fundamentals  
from quantopian.pipeline.domain import US_EQUITIES  
from quantopian.research import run_pipeline

# Construct a factor that simply gets the most recent total revenue value.  
total_revenue = Fundamentals.total_revenue.latest

# Add the factor to the pipeline.  
pipe = Pipeline(  
        columns={  
                'total_revenue': total_revenue,  
        },  
        domain=US_EQUITIES,  
)

# Run the pipeline over a year and print the result.  
df = run_pipeline(pipe, '2015-05-05', '2016-05-05')  
print(df.head()) 

The import quantopian.pipeline.domains should be quantopian.pipeline.domain (notice there is no 's'). Also, column= should be columns= (notice there is an 's').

Sorry for the confusion. See attached notebook.
